Automated user modeling for personalized digital libraries
Digital libraries (DL) have become one of the most typical ways of accessing any kind of digitalized information. Due to this key role, users welcome any improvements on the services they receive from digital libraries. One trend used to
improve digital services is through personalization. Up to now, the most common approach for personalization in digital libraries has been user-driven. Nevertheless, the design of efficient personalized services has to be done, at least in part, in
an automatic way. In this context, machine learning techniques automate the process of constructing user models. This paper proposes a new approach to construct digital libraries that satisfy user’s necessity for information: Adaptive Digital Libraries, libraries that automatically learn user preferences and goals and personalize their interaction using this information
Closing the loop: assisting archival appraisal and information retrieval in one sweep
In this article, we examine the similarities between the concept of appraisal, a process that takes place within the archives, and the concept of relevance judgement, a process fundamental to the evaluation of information retrieval systems. More specifically, we revisit selection criteria proposed as result of archival research, and work within the digital curation communities, and, compare them to relevance criteria as discussed within information retrieval's literature based discovery. We illustrate how closely these criteria relate to each other and discuss how understanding the relationships between the these disciplines could form a basis for proposing automated selection for archival processes and initiating multi-objective learning with respect to information retrieval
Automated legal sensemaking: the centrality of relevance and intentionality
Introduction: In a perfect world, discovery would ideally be conducted by the senior litigator who is
responsible for developing and fully understanding all nuances of their client’s legal strategy. Of
course today we must deal with the explosion of electronically stored information (ESI) that
never is less than tens-of-thousands of documents in small cases and now increasingly involves
multi-million-document populations for internal corporate investigations and litigations.
Therefore scalable processes and technologies are required as a substitute for the authority’s
judgment. The approaches taken have typically either substituted large teams of surrogate
human reviewers using vastly simplified issue coding reference materials or employed
increasingly sophisticated computational resources with little focus on quality metrics to insure
retrieval consistent with the legal goal. What is required is a system (people, process, and
technology) that replicates and automates the senior litigator’s human judgment.
In this paper we utilize 15 years of sensemaking research to establish the minimum acceptable
basis for conducting a document review that meets the needs of a legal proceeding. There is
no substitute for a rigorous characterization of the explicit and tacit goals of the senior litigator.
Once a process has been established for capturing the authority’s relevance criteria, we argue
that literal translation of requirements into technical specifications does not properly account for
the activities or states-of-affairs of interest. Having only a data warehouse of written records, it
is also necessary to discover the intentions of actors involved in textual communications. We
present quantitative results for a process and technology approach that automates effective
legal sensemaking
Relation Discovery from Web Data for Competency Management
This paper describes a technique for automatically discovering associations between people and expertise from an analysis of very large data sources (including web pages, blogs and emails), using a family of algorithms that perform accurate named-entity recognition, assign different weights to terms according to an analysis of document structure, and access distances between terms in a document. My contribution is to add a social networking approach called BuddyFinder which relies on associations within a large enterprise-wide "buddy list" to help delimit the search space and also to provide a form of 'social triangulation' whereby the system can discover documents from your colleagues that contain pertinent information about you. This work has been influential in the information retrieval community generally, as it is the basis of a landmark system that achieved overall first place in every category in the Enterprise Search Track of TREC2006

Understanding analogical reasoning : viewpoints from psychology and related disciplines
Analogy and metaphor have a long history of study in linguistics, education, philosophy and psychology. Consensus over what analogy is or how analogy functions in language and thought, however, has been elusive. This paper, the first in a two part series, examines these various research traditions, attempting to bring out major lines of agreement over the role of analogy in individual human experience. As well as being a general literature review which may be helpful for newcomers to the study of analogy, this paper attempts to extract from these literatures existing theories, models and concepts which may be interesting or useful for computational studies of analogical reasoning
