Title: The Jeopardy! Challenge and Beyond
Watson, named after IBM founder Thomas J. Watson, was built by a team of IBM researchers who set out to accomplish a grand challenge build a computing system that rivals a human's ability to answer questions posed in natural language with speed, accuracy and confidence. The quiz show Jeopardy! provided the ultimate test of this technology because the game's clues involve analyzing subtle meaning, irony, riddles and other complexities of natural language in which humans excel and computers traditionally fail. Watson passed its first test on Jeopardy!, beating the show's two greatest champions in a televised exhibition match, but the real test will be in applying the underlying natural language processing and analytics technology in business and across industries. In this talk I will introduce the Jeopardy! grand challenge, present an overview of Watson and the DeepQA technology upon which Watson is built, and explore future applications of this technology.

Title: Entity Sentiment Extraction Using Text Ranking
Abstract: Entity extraction and sentiment extraction are among the most common types of information extracted from documents. Both have been studied extensively, with different approaches. However, the problem of directly associating entities and sentiment has received less attention.
We assume that entities of interest have already been extracted in the document. Entity extraction is well-understood, and can be done in numerous ways. Also, we assume that appropriate word sentiment weights have been calculated. We use a training set of documents, where each document is associated with a positive or negative sentiment label, and use standard discriminative supervised machine learning to calculate sentiment weights for each word appearing in the corpus. We also use a stopword list and an absolute value weight cutoff to derive a relatively small set of word-sentiment values.
Then, we use Text Ranking (Mihalcea 2004), adapting it to use a bipartite graph of entities and sentiment-laden words and phrases, where entities and sentiment words are connected if within a configurable distance. We calculate the dominant eigenvector of the matrix corresponding to the graph; we then extract final sentiment weights to the entities, given all the contexts each entity appears in. Also, we can more accurately determine the sentiment weights of the words in the document given their contexts, as well as discovering the positive or negative sentiment “hot spots” in a document.
We then explore a number of related issues. First, we explore if (and how much) this improves the accuracy of the sentiment associated with entities in a document, compared to assigning the document's overall sentiment to all the entities in the document.
We also explore if (and how much) of an accuracy improvement there is if we track the entity sentiment over time. Then, we explore whether faceting on entity sentiment is improved using this technique in the context of search applications. Finally, we consider performance.

Title: IR Paradigms in Computational Advertising
Abstract: The central problem in the emerging discipline of computational advertising is to find the “best match” between a given user in a given context and a suitable advertisement. The context could be a user entering a query in a search engine (“sponsored search”), a user reading a web page (“content match” and “display ads”), a user streaming a movie, and so on. In some situations, it is desirable to solve the “dual” optimization problem: rather then find the best ad given a user in a context, the goal is to identify the “best audience”, i.e. the most receptive set of users and/or the most suitable contexts for a given advertising campaign. The information about the user can vary from scarily detailed to practically nil. The number of potential advertisements might be in the billions. Thus, depending on the definition of “best match” and “best audience” these problems lead to a variety of massive optimization problems, with complicated constraints, and challenging data representation and access issues.In general, the direct problem is solved in two stages: first a rough filtering is used to determine a relatively small set of ads that should be considered as potential matches, followed by a more sophisticated secondary ranking where economics considerations take center stage. Historically, the filtering has been conceived as a database selection problem, and was done using simple Boolean formulae, for instance, in sponsored search the filter could be "all ads that provide a specific bid for the present query string or a subset of it". Similarly for the dual problem (audience definition) for, say, a sports car ad, the filter could be "all males in California, aged 40 or less". This "database approach" for the direct problem has been recently supplanted by an "IR approach" based on a similarity search between a carefully constructed query that captures the advertising opportunity and an annotated document corpus that represents the potential ads. Similarly, in the dual problem, the newer approach is to devise an efficient and effective representation of the users, then form a query that represents a prototypical ideal user, and finally find the users most similar to the prototype. The aim of this talk is to discuss the penetration of the IR paradigms in computational advertising and present some research challenges and opportunities in this area of enormous economic importance.

Title: CloudSearch and the Democratization of Information Retrieval
Amazon CloudSearch is a new hosted search service, built on top of many cloud-based AWS services, and based on the same technology that powers search on Amazon's retail sites. Because of its ease of configuration and scalability, CloudSearch represents the next step in the democratization of information retrieval. This democratization process, increasing access to search for both end users and potential search providers, has continued over several decades, through technologies like early online metered search services, enterprise search software, web search, and open source search tools. CloudSearch further reduces barriers to entry, allowing a person or organization to basically say "make my content searchable" and have it happen automatically. CloudSearch may also offer an opportunity to overcome the stagnation that has occurred in search user experiences over the past 15 years. When you no longer need to be a search expert to make your content available, you're not stuck with ten blue links. Instead, you can focus on providing the kind of interaction that makes sense for your application and your users. CloudSearch enables a flowering of search applications that need not be tied to the web, and an opportunity to explore new ways of interacting with information retrieval technology.

Title: Putting Context into Search and Search into Context
It is very challenging task to understand a short query, especially if that query is considered in isolation. Luckily, queries do magically appear in a search box - rather, they are issued by real people, trying to accomplish a task, at a given point in time and space, and this "context" can be used to aid query understanding. Traditionally search engines have returned the same results to everyone who asks the same question. However, using a single ranking for everyone, in every context limits how well a search engine can do. In this talk I outline a framework to quantify the "potential for personalization", that can be used to characterize the extent to which different people have the same (or different) intents for a query. I will then describe several examples of how we represent and use different kinds of context to improve search quality. Finally I conclude by highlighting some important challenges in developing such systems at Web scale including system optimization, evaluation, transparency and serendipity.

Title: Making Web Search More User-Centric: the State of Play and the Way Ahead
Abstract: In this talk I will cover some critical challenges in web search, arising from the need to make it more personalized and user behavior driven. Some of the problems are more specific to non-English markets and users with certain cultural and linguistic background. I will start from the overview of several user-focused cutting-edge Yandex technologies, such as personalization of search by inferring the level of foreign language knowledge of our users and their socio-demographic features. Then, I will demonstrate how search can be improved using short-term and long-term user search context.
In the second part of my talk, I will explain how cross-lingual IR techniques can be applied to the problem of query understanding and will continue with such topics as balancing relevancy and freshness in search results and query suggestions, and adapting off-line and on-line retrieval quality measures to the real-world demands.
I will also overview various recent initiatives started by Yandex, aimed to support public research and engage the IR community in exploration of advanced topics in web search in order to consolidate and scrutinize the work started at industrial labs.

Title: Related Searches at LinkedIn
Search plays an important role in online social networks as it provides an essential mechanism for discovering members and content on the network. Related search recommendation is one of several mechanisms used for improving members' search experience in finding relevant results to their queries. This talk describes the design, implementation and deployment of Metaphor, the related search recommendation system on LinkedIn, a professional social networking site with over 160 million members worldwide. Metaphor builds on a number of signals and filters that capture several dimensions of relatedness across member search activity. The system, which has been in live operation for close to two years, has gone through multiple iterations and evaluation cycles. We will describe the signals used in Metaphor, their scalability, and the practical concerns in deploying related search recommendations.

Title:Towards Summarizing the Web around Entities
Abstract: We want to approach the challenge of how to best summarize content published on the Web. Our ultimate goal is to be able to answer questions like: “what does the Web know or say about X?”, where X can be some entity of interest. It is our belief that pivoting multi-authored and transient (e.g. user-generated) content around concrete entities such as persons, organizations, locations, etc., but possibly also around abstract concepts, provides a sensible organization principle that offers a value-add to users relative to the views of the Web created by search engines, news / blog sites, or social sites.
The above challenge naturally decomposes into the following
subproblems: (i) entity base curation, i.e. semi-automatic generation
of a catalog of entities alongside with information around relations
and naming, (ii) entity linking, i.e. automatically detecting and
linking entities in Web documents, (iii) document or entity mention
clustering, i.e. grouping related (redundant as well as complimentary)
documents or passages together, (iv) multi-source summarization of a
given cluster relative to a query entity, (v) summary display, where
we investigate timeline views. Obviously, each of these subproblem is
a significant challenge on its own. The purpose of this talk is thus
not to develop near-perfect solutions to any one of these, but to
present an end-to-end prototype system, which is a first step towards
the ambitious overall goal.

Panel Chair: David Hawking, Funnelback
Abstract: The early pioneers of IR would probably be flummoxed (or even gobsmacked) by the scale, diversity, pervasiveness and economic importance of current industrial applications of IR research. They would no doubt also be delighted at the extent to which industrial applications have extended research frontiers and spurred further discoveries. The 2012 Industry Panel will canvass the diversity of IR in modern practice and will explore differences and similarities in viewpoints between stakeholder groups. Each of our distinguished panelists has been asked to attempt to represent the likely viewpoint of a particular group or “vertical” while responding to a series of questions notified in advance. These questions will cover perspectives, perceived challenges, opportunities and roadblocks. Trystan Upstill of the Search Quality Team at Google will represent “large scale web search”; Jerome Pesenti, Chief Scientist at Vivisimo / IBM, will represent “enterprise search”; Krishna Gade, Engineering Manager at Twitter will represent “real-time and social search”. Stephen Robertson, Emeritus Professor at City University, London and MSR will represent “academic research” and Diane Kelly, author of an influential Foundations and Trends monograph on user-involved evaluation will take the all-important perspective of “users”. The audience, too, will have their say!
David Hawking was a Coordinator of the TREC Web Track from 1997-2004 and
