Outline Characteristics –What’s unique with scientific literature? Functionalities –Possible utilities based on the characteristics Prototypes – es_and_search_engineshttp://en.wikipedia.org/wiki/List_of_academic_databas es_and_search_engines

Scientific Literature: What’s Unique? Structured content: –Title, author, abstract, conclusion, reference,.. A latent network structure: –Reference; citations; co-authorship Contexts: –Time, conference/area, authorship,... –Citation context What about the content & language? –Topic dense? Terminology rich? Definitive language? –Controlled vocabulary? Low noise?

Managing Literature: What can We Do? Structured content: –Full text search, structured search, citation search –Similarity search Latent Network structure: –Citation navigation, co-author navigation –Co-citation Analysis, etc –Community analysis Context: –Trend analysis, author comparison, interdisciplinary research identification, … Language: –Topic extraction & categorization, filtering, concept analysis, ontology, summarization, …

Example Systems CiteSeer, Libra, Rexa, SCOPUS, DBLife Who did it? What’s their unique feature? What’s not covered?

CiteSeer Penn State Similarity Search Citation Context (partially) Citation Trend Statistics

CiteSeer: Similarity Search Content similarity Sentence- level similarity Co-citation similarity

CiteSeer: Citation Context

CiteSeer: Citation Trend

Libra Zaiqing Nie, Microsoft Research Asia Community search (topic extraction?)

Libra: Community Search

Libra: Author and Community

Rexa UMass, Andrew McCallum Search for grants, Tagging Topic extraction & categorization

Rexa: Tags

Rexa: Topic Extraction & Categorization Topic Relation: Citing, cited, co- occurring Trends

DBLife Anhai Doan, U of Wisc. Integrating heterogonous academic information Change monitoring Not much on literature Many prototype functionalities

DBLife: Integration

Discussion: What is not Covered? Features: –Citation Context Functionalities: –Filtering; Summarization Opportunities: –Comparison across contexts –In-depth community analysis –More useful classification –…–…
