SIGIR Conference on Research and Develop in Information Retrieval SIGIR 2020 SIGIR’20 Chairs’ Welcome Welcome to the 43rd Annual International ACM SIGIR Conference on Research and Development in Information Retrieval (SIGIR 2020). SIGIR is the premier scientific conference in the broad area of information retrieval. According to the original plan, SIGIR 2020 would be held at Hyatt Regency in Xi'an, China. Xi’an, known by most people as home to Terracotta Army of Emperor Qin, is one of the oldest cities in China. The beautiful Hyatt hotel was also carefully chosen after we had site visits for more than 15 local hotels and done frequent communications with experts and professionals across academia, government and industry. Due to the pandemic of COVID-19, the organizing committee of SIGIR 2020 decided to move this year’s SIGIR fully online in April. Thus, our conference this year becomes the first virtual one in SIGIR history. This last-minute change of the conference posed many challenges and much burden in terms of preparation and sponsorships. Despite the shortened time period and challenges, General Chairs, Vice Chair and their local organizing team worked very diligently to carefully prepare an outstanding program for everyone. This year SIGIR has received a record high number of submissions in its history, as shown in the following statistics. This trend suggests a renewed interest in our field. We were happy to observe the highest number of submissions for long, short, industry track and demo papers, which sums up to 1,180 papers. The accepted papers were made by 1,221 authors from 32 countries. • 555 and 507 valid submissions for full and short papers respectively • 80 effective submissions for industry track papers plus 38 demo papers

  • Basic Concepts in Information Retrieval
    1 Basic concepts of information retrieval systems Introduction The term ‘information retrieval’ was coined in 1952 and gained popularity in the research community from 1961 onwards.1 At that time the organizing function of information retrieval was seen as a major advance in libraries that were no longer just storehouses of books, but also places where the information they hold is catalogued and indexed.2 Subsequently, with the introduction of computers in information handling, there appeared a number of databases containing bibliographic details of documents, often married with abstracts, keywords, and so on, and consequently the concept of information retrieval came to mean the retrieval of bibliographic information from stored document databases. Information retrieval is concerned with all the activities related to the organization of, processing of, and access to, information of all forms and formats. An information retrieval system allows people to communicate with an information system or service in order to find information – text, graphic images, sound recordings or video that meet their specific needs. Thus the objective of an information retrieval system is to enable users to find relevant information from an organized collection of documents. In fact, most information retrieval systems are, truly speaking, document retrieval systems, since they are designed to retrieve information about the existence (or non-existence) of documents relevant to a user query. Lancaster3 comments that an information retrieval system does not inform (change the knowledge of) the user on the subject of their enquiry; it merely informs them of the existence (or non-existence) and whereabouts of documents relating to their request.

    Information Retrieval (Text Categorization) Fabio Aiolli http://www.math.unipd.it/~aiolli Dipartimento di Matematica Pura ed Applicata Università di Padova Anno Accademico 2008/2009 Dip. di Matematica F. Aiolli - Information Retrieval 1 Pura ed Applicata 2008/2009 Text Categorization Text categorization (TC - aka text classification) is the task of buiding text classifiers, i.e. sofware systems that classify documents from a domain D into a given, fixed set C = {c 1,…,c m} of categories (aka classes or labels) TC is an approximation task , in that we assume the existence of an ‘oracle’, a target function that specifies how docs ought to be classified. Since this oracle is unknown , the task consists in building a system that ‘approximates’ it Dip. di Matematica F. Aiolli - Information Retrieval 2 Pura ed Applicata 2008/2009 Text Categorization We will assume that categories are symbolic labels; in particular, the text constituting the label is not significant. No additional knowledge of category ‘meaning’ is available to help building the classifier The attribution of documents to categories should be realized on the basis of the content of the documents. Given that this is an inherently subjective notion, the membership of a document in a category cannot be determined with certainty Dip. di Matematica F. Aiolli - Information Retrieval 3 Pura ed Applicata 2008/2009 Single-label vs Multi-label TC TC comes in two different variants: Single-label TC (SL) when exactly one category should be assigned to a document The target function in the form f : D → C should be approximated by means of a classifier f’ : D → C Multi-label TC (ML) when any number {0,…,m} of categories can be assigned to each document The target function in the form f : D → P(C) should be approximated by means of a classifier f’ : D → P(C) We will often indicate a target function with the alternative notation f : D × C → {-1,+1} .

  • Information Retrieval System: Concept and Scope MODULE - 5B INFORMATION RETRIEVAL SYSTEM
    Information Retrieval System: Concept and Scope MODULE - 5B INFORMATION RETRIEVAL SYSTEM 15 Notes INFORMATION RETRIEVAL SYSTEM: CONCEPT AND SCOPE 15.1 INTRODUCTION Information is communicated or received knowledge concerning a particular fact or circumstance. Retrieval refers to searching through stored information to find information relevant to the task at hand. In view of this, information retrieval (IR) deals with the representation, storage, organization of/and access to information items. Here, types of information items include documents, Web pages, online catalogues, structured records, multimedia objects, etc. Chief goals of the IR are indexing text and searching for useful documents in a collection. Libraries were among the first institutions to adopt IR systems for retrieving information. In this lesson, you will be introduced to the importance, definitions and objectives of information retrieval. You will also study in detail the concept of subject approach to information, process of information retrieval, and indexing languages. 15.2 OBJECTIVES After studying this lesson, you will be able to: define information retrieval; understand the importance and need of information retrieval system; explain the concept of subject approach to information; LIBRARY AND INFORMATION SCIENCE 321 MODULE - 5B Information Retrieval System: Concept and Scope INFORMATION RETRIEVAL SYSTEM illustrate the process of information retrieval; and differentiate between natural, free and controlled indexing languages. 15.3 INFORMATION RETRIEVAL (IR) Notes The term ‘information retrieval’ was coined by Calvin Mooers in 1950. It gained popularity in the research community from 1961 onwards, when computers were introduced for information handling. The term information retrieval was then used to mean retrieval of bibliographic information from stored document databases.

  • Semantic Information Retrieval Based on Wikipedia Taxonomy
    International Journal of Computer Applications Technology and Research Volume 2– Issue 1, 77-80, 2013, ISSN: 2319–8656 Semantic Information Retrieval based on Wikipedia Taxonomy May Sabai Han University of Technology Yatanarpon Cyber City Myanmar Abstract: Information retrieval is used to find a subset of relevant documents against a set of documents. Determining semantic similarity between two terms is a crucial problem in Web Mining for such applications as information retrieval systems and recommender systems. Semantic similarity refers to the sameness of two terms based on sameness of their meaning or their semantic contents. Recently many techniques have introduced measuring semantic similarity using Wikipedia, a free online encyclopedia. In this paper, a new technique of measuring semantic similarity is proposed. The proposed method uses Wikipedia as an ontology and spreading activation strategy to compute semantic similarity. The utility of the proposed system is evaluated by using the taxonomy of Wikipedia categories. Keywords: information retrieval; semantic similarity; spreading activation strategy; wikipedia taxonomy; wikipedia categories 1. INTRODUCTION fashion than a search engine and with more coverage than WordNet. And Wikipedia articles have been categorized by Information in WWW are scattered and diverse in nature.

  • Introduction to Information Retrieval
    DRAFT! © April 1, 2009 Cambridge University Press. Feedback welcome. 1 1 Boolean retrieval The meaning of the term information retrieval can be very broad. Just getting a credit card out of your wallet so that you can type in the card number is a form of information retrieval. However, as an academic field of study, INFORMATION information retrieval might be defined thus: RETRIEVAL Information retrieval (IR) is finding material (usually documents) of an unstructured nature (usually text) that satisfies an information need from within large collections (usually stored on computers). As defined in this way, information retrieval used to be an activity that only a few people engaged in: reference librarians, paralegals, and similar pro- fessional searchers. Now the world has changed, and hundreds of millions of people engage in information retrieval every day when they use a web search engine or search their email.1 Information retrieval is fast becoming the dominant form of information access, overtaking traditional database- style searching (the sort that is going on when a clerk says to you: “I’m sorry, I can only look up your order if you can give me your Order ID”). IR can also cover other kinds of data and information problems beyond that specified in the core definition above. The term “unstructured data” refers to data which does not have clear, semantically overt, easy-for-a-computer structure. It is the opposite of structured data, the canonical example of which is a relational database, of the sort companies usually use to main- tain product inventories and personnel records.

  • User Centered and Ontology Based Information Retrieval System for Life Sciences

Besse, 30 035 Nîmes cedex 1, France [email protected] 2Laboratoire de Paléontologie, Phylogénie et Paléobiologie, Institut des Sciences de l’Evolution (UMR 5554 CNRS), Université Montpellier II, CC 064, 34 095 MONTPELLIER Cedex 05, France [email protected] Abstract. Because of the increasing number of electronic data, designing efficient tools to retrieve and exploit documents is a major challenge. Current search engines suffer from two main drawbacks: there is limited interaction with the list of retrieved documents and no explanation for their adequacy to the query. Users may thus be confused by the selection and have no idea how to adapt their query so that the results match their expectations. This paper describes a request method and an environment based on aggregating models to assess the relevance of documents annotated by concepts of ontology. The selection of documents is then displayed in a semantic map to provide graphical indications that make explicit to what extent they match the user’s query; this man/machine interface favors a more interactive exploration of data corpus. Keywords: Information Retrieval, Semantic Query, Visualization, Directed Acyclic Graph, Aggregation Operator. 1 Introduction As the number of electronic data grows it is crucial to profit from powerful tools to index and retrieve documents efficiently. This is particularly true in life sciences where new technologies, such as DNA chips a decade ago and Next Generation Sequencing today, sustain the exponential growth of available data.

These disputes are well-known to those who study the Internet's international controversies.1 But not everyone realizes that these controversies are also forms of trade disputes, and, as such, no one yet fully understands how the law of the World Trade Organization ("WTO") might affect them.
