Abstract  This lecture gives an overview on Information Retrieval. It explains why documents are ranked the way they are. The lecture explains the most relevant ways for content representation: Automatic indexing and manual indexing. For automatic indexing, the frequencey of word is of special relevance and their influence on the weighting of term are discussed. The most relevant models are introduced. The session on evaluation discusses new metrics like the Normalized Discounted Cumulative Gain. The session of information behavior provides a brief overview and explains the relation to IR. The session on optimization mainly introduces term expansion and fusion methods. The session on Web retrieval is concerned with the quality aspects and gives a basic insight to the PageRank algorithm.

how can we optimized information came systems of fuel techniques that will discuss the 1st do we need that was like to bring some example strong real world systems for example you
00:15
bring nice Systems the subgrid from continental the basic
00:24
things don't work here but it was the cause a 10 year period in the dividend and the result was all walks if you
00:40
want to know what is but
00:44
interestingly you don't find the result for the basic for me but for the more they find for with the and at the end few sold see even get to the city to find something to suit and not with the basic for that strange actually happened at the same time when somehow wrong for 1 of the world rather large companies not big
01:16
some somewhat was works are in the middle of of all results and the and the visitors who will you
01:26
will find the the using sacked the Oh by the way end of the year end of all over the world and in the game do this the Rossi across a simple general written simply don't you can find the soul of
01:48
investment mechanised side the search will not be meet the use of this document disputed
01:58
document soul uses will find it and investment is basically a her
02:06
all sold in the EU by the book the special carried the problem near the of a show in which the size of the Isle of the Dead was seated at the head of the division of the company has something to offer it could be due to special care
02:37
on the issues to maintain the finding that all of the money will be named this is somebody who is on the board of the company and you find some results but we don't find the least of the board members of the SAS and strangers and that it should be billowing company and it
03:05
should be directed to use David
03:09
solo issues still area of the cost of this is that the children were going to for to be combined and strange another entranced by does not have any result for position to see what could be the case for suitable that a should just after the actual behind the wheel face to and the words but allegiances besieged by the French types of travel insurance something with between is a travel health and this section what I'm looking for and there is a travel was called pleasant to to secure the early the shame if you can or travel you get reversed a money to English term for that they were there could be a problem of terminology before such as and want by indeed this issue supplies of those seeking recent rise issued a we see that they actually offers something but this simply the different Tumilovich the rise of the human said of transition to security such a better job to
04:47
see the should look for what to be public people call this strident and at this to the the days also has a company was in the evening there is that it is somebody might be and you'll be able to sell 1 launches in UK so that the law of the for
05:09
a movement in today's such technology and will provide discussed East Optimization methods to inform this rather than the back premodification will focus on the response to methods and future also through the the statistic version of the FMM even managed to get to the city free comes out and
05:39
Radomski where all the technique that is small to were extremely well so if you can meet with a 5th of all the leading to improve the quality of speech this is the most beautiful of all to the good and the average length of refuses to point something that were 3 words that saw much on DC so that it would be better to give more information to be damaged before I'd like to say that the chance of getting a good fit think of more chance just at the point where for for you might think but not the back the BigSim Miller and also sells the user please provide more information the struggles some of the global currency takes time by the the efforts of people like to woman but as possible these and log on to speak of the need for all this again to remember come up with some time memory not just not searched the so continued ended up 2 places OK just the prejudice and a few times then went to see the results of the cells that we want the problem with the current state of says the system will say that this was relevant this was dissident said anything about how what this I really want to help us see what does he mean when taxis to terms with the news sites in the world as we know from NYTimes enough the Sixties to documentary for this difficult for these 2 of last 5 more documents that have also been should be area but they are also likely be documented are judged as relevant so this is the most more about your need much information the by using this is relevant soul
08:05
is to that reiteration while the walk from the ruins of the the old relations abolition of viewing 1st by a brutal regime to use all the something that we would like to look at some of the for this size and this is a mental over dual carry anyway not just with the system and in
08:34
March this maybe this needs to be some the show's attractions methods like jet also something mocked the remote once and the system will be in for cruel so this to more from each year and that the union
08:54
of the world record for the world's you would get results in the 1st year but this is the point of the show to be ring on all of these documents also and was close friend use of walking into room the we used by month example while free of frequent than the average in the collection and maybe the sun interesting for so give these so we at the stumps to the cream the if you should be reading now we get some of its fixed rate of relevant documents we get along the incentive plan to the system for the 2nd courage the her so these should
09:59
is of course the really information 2 at the rear of documents to the future of this options were all costly
10:20
ahern baking Britain's but they need to be the results but unfortunately almost full system really of was while he was still like to do and it's a game that interaction step once did that the results of look at them and they don't want both the 2nd and 3rd and 4th and it would be long that this would be the sole a busy with such a small book of into action is not accepted by most use the and that is why system developed this came up with the idea of going blind relevancy would is blind residents who is the same thing justified reviews from which the we do iteration we get results all the which of the thought of all that we are information agreed we assume the 1st time documents on charges in this we get back to the system and that after the relevance to the wicket 2nd result from you the and this is presented so automatically be extended the extent of the races of the small towns far schemes we do it that way we might also improve on just liable to those relevance
11:52
to the island the user attraction system just assumed the pub in 10 20 30 all relevant and expect some they fight for what returns from the end at some of the add
12:13
that could just illustration of searching in this as in so the real the
12:23
commission questions on roads to not yet Casole when the
12:32
Bagapsh just 1 technique within the family of techniques and all called the expunged freaks bench the goal of this all ways to give more information to this is to have more than music as a way of mission is typically so we have a really sure to be tried to get different terms for fully while useful for this vision so we have use the latest location but it also premodification about using we are glad to see that discuss but there all the time 0 where is also the knowledge based in ball saw as we talk about this sort of thing about the book and the next thing I saw was the subject of an relations and do it all over the world all his insight into the game with a lot of people at the top of his off the suggest something that we are making that for the 1st to include The Who Wants to Be include so suggests that the uses the let the function for not is so users will not be reasonable now we have to discussed of published based in automatic expansion of simulators that have something to do with the the creating and might be used it on the 1st day of
14:37
interpretation of the law rather than sit back to the club in the wake does a small basically returns to the stage where he is moving to the wall was the results the Sunnis the fastest on bottom is the judges of the of the year but this is likely to be this day of all this is rather than as is that of the new issues Bush will also words by the rules by which would be was about as far away from the view that this is a radical interpretation of the but ApJ
15:40
earned and remember again rather and see how it was something that we or a discussed in the context of the follow network model of staying at the age in name their Wigan have to the single and you take technique there was being here and the last in the network functions of spreading which kicking injected interested any point it's result in the good times he would after 1st situation the 2nd and its the sole second class on Wall said it looked as if you
16:24
would like you so rodents feedback close the documents the logic of the regions they came
16:34
at under Riversimple most select a rookie over time for allowing them to stay on my you want is to be used last over of the day we might all the of echoes those of the appointments and sub tracked the ones from the unit that Sarava stupid technology the of
17:04
the waste to the and by the middle of the the road to it
17:10
but there are also something might not should be able to explain what 8 months typically used to look for for the same on what this term expansion not much based expansion based on a storey that will cost the group which also includes a number of resorts to each of us has discussed the matter with the Mexican was consistently fixed among how we don't call it comical the order of ONg so a Case somebody was in the car in the library for example the system should although became in the we all read that autumn the American it also accuses searches for public can also directly Petrotech with the board the of cause Sunos related for the to those who like to think that we reach the summit on the use of type this word but the dish no and and mean the same thing example are also more than on a more by his more necessary may minivehicle that's and this to be the name of all that I use in the home and hopefully than you could returns to make things happen also critical moves unlike could also be the only place where you find anything ready for the results to the Tel the user really that even find anything Continental that at some sort or by the finding that uses for all I'll find anything with banque fillets gave him something financially to situation drug they and their meat is or think some of the a new window on rebel sold
19:28
interesting results for because of all the news for the ball but the talks on the eve of this of those sizes in Germany says this is pseudonym but we prefer starts on time for stretch anticipat time and if somebody who starts on should be directly from the 20 and the sinking of cost for the index dank again from looking at
20:14
spreading activation networks something that happened automatically remember that enter the than commission spreading to interest result the network to the document this prospect and also the fund terms were activated and but also to those with a related terms and that was that will the makes that long
20:46
not so we want to find related to of you need you the detected a teachers when up 2 terms seem a love of the game in terms of information Tree any ideas into a change of clothes for the new his said will be possibilities don't look good with the fact that they are not you see close that looks but also in the words like but there will have a lot of finding something like Law and Order all be called off because the spell but a confined things like that all Dixon she P M 2 of 4 so before you know Luton so cosy during the period but the picklocks considering what the people the accepted as a kind of such although you would as a result that is possible to assumed that taking in viewing a result this is some sort of tournaments and and we have some elements information than became Bruce's we can uses accepting the same way as a reference he has a long term remains banque and that use of future injections generally also adding this year a rate of the days 1 session but the mixed use it something of a not offered there is a different approach in the the looks some surgeons and use yes possible but we don't want to talk about what she was but it's different he for a night the take that that term is symmetry to P the where was the the 1 the British yes and it is almost like his own but very soon before the start of public it a bit fine to some of battle were banque the user and debate 1 a fine related terms to spend this sort of much of the extent that they have used a forest of public domain who work for it to work goes into his owners would want with Automatic now that the only change in the law that would allow people were found dead in the water with the fact that would be a lot of longer than guess S possible Moissac all the fact that we have learned that it is accepted the description and the Foreign and bundled into a children's perfect description of the possible way 1 of 1 of the great but they are not cost of images of moving the as a more general approach the Gulf to simple way the SCF it data structure that we have what was up what describes all collection after mixing bookham intimate Shi'ite we have a well you for each time which document that describes the like this and how we want to see
25:41
the began with simple so following who during the said that the document which will be written really has 1 of the views of the economy it is too early so regarded the area is being these subjects what they also work would it is that you realise that what we get to in the way we used by the goals of the that the is simulates also and that means the to just like his face it is with all the off the wall and beat Westwood the vote was a very who was goaled for all used by the fact that some of the slack where we have a really good are as it were and are all the time because there is not cheque whether it was in the days of the year and but it was as if this is indeed a good but in a context it viewed in the context computer same documents we have a higher chance of being seen to have accepted this year and differences but the Philippine Computing different context and never all together in the same documents that we assume these terms but that's a very mathematical way to look at the men expected below anything about the words were just
27:54
assumed and that means associations recall this
27:58
Association relations
28:01
Burns objects once experience tend to become the associated with the machinations of the 1 so that any 1 of them is far from the site of also all the qualities things all remember things associating them even if that are having to do with the objective and the
28:27
tree lined mathematical with the of situation Calker current of terms to get the in documents on Association associated cruises from something from the chorus of things off by simulator whose also SoJewish systems to recommend
28:50
India also something we can happen for below them with the speed and the British pound version but in this version the could look for something that scene in the pages of the system accepted populated this
29:04
between lines and now we look at the case but costs but we have exactly the same as in area of the needs of the region but we all the ap but many the on of the so we don't have to know what is worse really mean
29:35
in this case to could easily have cost
29:36
say yes there is there has a high these were also reduced for the piece to the beauty of this is there is to called fixed which 1 Richard and was about to institutions and the subject of losing some City area that all of those are in the city st James this so he
30:23
would have speculation and now we end
30:26
up with the simulator value as the marriage Matrix between all the terms in truth mobilise we have programme about what will be the major just where you want but we see the end of the money or anything but part of their house body and also the lovely particle suited words of Jews you should be in which the case was a and the and now the the single seater booking so if they they are not bothered about the men's there is that he is 100 and there is another term the that using night you will the of their disease for a pat on the back of a set of photographs of the people the size of a soul in the junior is 1 of the reference to the way you want it just when you have all the appearance of documents determines the association volume in between Ms between words for the 1st based on the book by the the new diary that some part a set of the follow up to to remove the
32:39
bullet was do some or all of its volatilisation was that is because the public would year old for the part of the reason and diseases of all of these are due to use of size what were all eyes singular geometric treatment of cost expected although they don't buy
33:13
animal where you have to 1 many of those who do this fighting this catches the local question hopefully result because it is such a simple Matshiqi could explain if for the which but she looked so could
33:43
remove on so all these days ago associations with the Blue you usually used for all said part being is we see the world Neil singles and associated with the England major something in which is the only bit of the book Max it is very close to what the image of British shine says that word that the media were but 6 using language distance accepting basic looked to via the euro's sophistication of documents that between and he moved to the we do anything about the meaning of the view that the sky humans OK and that is so much to the extent
34:49
that it was a good look at the Suez and get them to the right so that the response the from the also use of sue the relevant because of all the expulsion whose based on launch these sizzles all Wallowitch but extract from the collection by the public all that is the expulsion response bedding more firms to be because we have more chance the success opaque 18 questions not move on to to the next but the fault of demise a show that is but with the here and now
35:40
owns fusionists closely related to ministers which also called rank aggregation but it's a bit different from the US we are basic during all of the vision of the future means we have different ranking algorithms different indicators of from different sauces and we want to bring them together and you want to have several evidence and if you there the is scale the changes to way the people of all of all of this was the biggest of data on the eve of a long they so ready the the basic ring together to islands and that was when we talked about big announced was said we have to be trained by the and we have all seen the direct you money we have to bring them together to come up with some final results for the full with which they receive by adding that the the with the multiplied but we do have a great it now we will see that the different ways to bring it is also clear that the recent a ones but why do we
37:15
do fumes reporting season which will be on the site is to use all the help they all quite whose is playing best the 1 there were 4 of us we can also follow the rest of the systems that made by a summary of the following the EU and the US a meaningful because that is the difference in the base of the bridge the closing is only were so yes on average embarrassing but system they might find the fund relevant documents insisted that is there to do so we could simplifying we could say that has if an average was fined different 8 but overall all that the single celled ideal the to bring them together and a chance to find out and the and the only before Madrid into 1 joint list that slightly fusion algorithms
38:42
are a positive on the roads in the text for that and this is
38:51
related to some of the media machines several of his book together like in machine learning from we have different from experts said that the metaphor is an expert meeting before people come together to bring their opinions level we the Comique of some of the decisions in the usual and that is what it last algorithms in the I'm machine earnings for me machines for information to computer was sometimes rank aggregation the
39:30
Act also number that she will fusion is also all of this will be several search engines for a while and there is even worse than the kind that there is huge interest in the operations of the ascent of of the Red which is a very constant value in the growth of the way and then the ideas and several such engines to get an average infusion get his different we have hours before each of these new estimate for each document download it might want to look like a picture for
40:17
job well there is a a goal that is also the of knowing that we are a long way off but the restoration of the case as walls this is the book for what they would do that this is or the the key to what must be the 1st full day of the dreams of a specified used july 3 was the album giving but to bring these large together 1 ranked for the use what a paedophile but demand the but now but act 1 eating following a cosy what these from the world's worst of all worlds it it was the perfect solution times not a producer of the show was being these innovative means the Act which to over said that the only seeing and look at if so if you see is not what operating in the UK with the but this great of shapes and sizes we will tell the storey veteran voltage Act time for is created by a team of they but it is easy to all these was easy to create the it must be because of a slight the part by some or all of these pages will relocating where to Facebook agreeing to come to the which to a summary of the of the region and that is because I realised for the 1st time gusts of 6 1 by by the but it was a book that will be much lower for all through the night they but wealth and of the way we used to joke we have a close look at and this absolutely comic book position that the the less but what they would be used only once Louis the size of a other reasons for me 4 erm while but only 1 of the ladies in the UK said that the case should be that it is a good for this 1 with a 2 1 the numbers of those in the know where all used to be full of the sort that all of these office is also which has the highest has lost their families to use of the use of so analyze is not been checked for the the Secret Life of another because the fertiliser this is what cheeses long and this is what for another other violence Blue tackles J poisoning where they have in this case it is the act of with those of the show that the party is over for the boys this lies with the the early part of the the ways to do this the 1st of 6 some
46:11
these are could also felt something and transparent richness of Phil to upgrade
46:16
but basically would really want
46:19
is to make in the make 1 ranking from 7 several different ways
46:24
very simple his round robin approaches to be the 1 from which it at the time if I saw reading the least and I don't do anything other than what we all want to use up for all these reasons it was the real thing the next week falls only of a position that would also allow the location of the site will that right on Feb 0 which some evidence is expected this is really about of the neck and we know we aren't all the suit for multiple ending up because they so that you get the same thing really good reproductive and said so the from efforts here is an example for
47:24
mobilisation the police have got so we have won and the role won by 0 for an area to be reconciled values the at the end for a for quite easy but if you know which function to use to consent to huge machines
48:00
behind we distaste just to show cost of future and their minds at the moment it was maybe are on road makes and last not we have to all the usual searches and the fact that for future sometimes we some of the public in which 1 is the best assault road written to reach this should be a where you should know that the cost different fusion functions and read the to re written difficult last and but the distance and the and the time Bravo insist they would so thoughts of says this is is thought to be so great as long as it was close to this week but the again this is also the during so that on the next 1 see all the regardless of the P but what of the rest of the IAAF higher draw put point out from the deletable services but at the end the ability of each each never go near 5 feets but would not be used out of their you way see what what about all the part Bishop of its to act is now but across the thing that you can understand that the world was at work that but was not the result of someone who was a long time Hunt's Jake called wrong but pointed based actually by the US by a of 1 point 0 or this the is also or what we want to do to Britain is it the same seeks also ordered his side confused much confusion about
51:01
this occasional you know all the Cabinet sounds and multiply and the maximum right very strange for questions Peugeot also abelia
51:19
combination would be prevented each algorithm and said this is a good idea of this such that every parent by time
51:28
these which could be could change
51:31
in reproductive from scoring methods were plans for breakfast and the gin into examines the for long
51:39
term savings interestingly there also systems that actually to do so from the search
51:48
for example of affable the at the gates of on line any more but with quite a nice
51:53
system where you search a version 3 government baby and aggravated assault to all you this is the 1st result I are in the presence of the disease of 1st result will might reviews this is the 1st result of it was last night locked is that we should be on all that was wrong they just for the way during the with up well this is all good rather than good work the review made the highway should also after because all the coach the gates of the long unable to them and say that this is what we expect the should this is something like the you said that that take turns Tiffini should but from a different perspective sold out German gaming tables
53:21
results even while the potential says that is not such a good to and especially as is of some of the worst violence by the end of approach to to work with what combined Computing different making men this some potentially diffusion pressures
53:50
human that this response with a long then we jumped over
53:58
results accuracy the and
54:04
we come to the last public to question on to the pressure on stream from Bristol of the new of evil this the is of used only automatic end up with a documentaries as result into the land of the free from which they have to read the document finding which but the sent being
54:37
allow the user to ask the questions that have been used in the evening by the results extracted in giving the fact as an answer run on to assess Rangers instant 19 87 as the research on the stock picking turns so giving the small the basic ideas to to retrieve and then extract small caution be sentence be a word from the book and that is the the answer to the question of but the question right so here we find
55:16
out that these are the record of the presented so 1 way so what the challenger to a systems have stayed Campbell kind of information is the real reason 3 ghostlike where this something that all where that means to find a place for all the answer most that places to use and love furniture negated the recognition tools that we ought names and actual of placenames extract and find the right and of cost that's not so trivial we have to know how to react and supplied attacks on the World Cup was the where with the full and they have to be able to not only to the mixing and the tree but also to add extracted sentence and expect exact ends so in addition to the standard technology that we need would be moving in the right place hours and that the real cement earth the critic and cricket jumped
56:41
over base for example Christian taxonomies we have different
56:46
things used the examples of question which city in official was interested in the future for the remainder and home many evidence has placing on the grid density of the number of all eyes and but only about half an this says can
57:07
be quite effective on some systems which between 4 and 6 per cent and interactive systems can be created in the
57:19
example of the ball because of injuries in German but also has a lot of which was to use the at all times of and but there are various receive there is a sense that the spectacle of the year and
57:46
also he we never systems on the Web to the new rules and the Brit lexicon for example where the title the review of be in the 1st said which the American you get some of its states in the systems but question you would is
58:12
the size of the move by point in the 9th get some answers to oust the board of England where the and the rest of my career is 1 4 inch of a sense of what the under the new laws but with technologies up to no
58:44
this system stop system that still on the line again here and was between standalone period use all the the tools at with the Lions he on the river Bristol for the sausages the year but it is to see his face the don't of want the themselves in New York of the results if the sauce is giving the same and so might be so
59:24
try these things Storace also system that you can you lose some of whom were given a fuse to need to do all the work to be able to work with the point of the exam in Britain to walk into the media so basically groups that have to talk about to date on any further questions on the example
