GEAR-Up: Generative AI and External Knowledge-based Retrieval: Upgrading Scholarly Article Searches for Systematic Reviews

Project : Systematic reviews (SRs) - the librarian-assisted literature survey of scholarly articles takes time and requires significant human resources. Given the ever-increasing volume of published studies, applying existing computing and informatics technology can decrease this time and resource burden. Due to the revolutionary advances in (1) Generative AI such as ChatGPT, and (2) External knowledge-augmented information extraction efforts such as Retrieval-Augmented Generation, In this work, we explore the use of techniques from (1) and (2) for SR. We demonstrate a system that takes user queries, performs query expansion to obtain enriched context (includes additional terms and definitions by querying language models and knowledge graphs), and uses this context to search for articles on scholarly databases to retrieve articles. We perform qualitative evaluations of our system through comparison against sentinel (ground truth) articles provided by an in-house librarian.

Twitris is a Semantic Social Web application for extraction social signals and understanding social perceptions by Semantics-based processing of massive amounts of event-centric social data. Twitris 2.0 addresses challenges in large scale processing of social data, enabling us to understand events along spatio-temporal-thematic-sentiment dimensions. Twitris 2.0 also covers context based semantic integration of multiple Web resources and expose semantically enriched social data to the public domain. More recently, Twitris is adding People-Content-Network analysis, real-time support (using Twarql), and continuous semantics.

Trusted Perception Cycle

SemSOS is an extension of SOS to allow SOS queries and access to an ontological knowledgebase. Main contributions include: (1) sensor/observation ontology based on Observations and Measurements (O&M;), (2) semantic annotation of O&M; and SML documents, (2) mappings and translation scripts to convert O&M; and SML into RDF (and vice-versa), (3) rule-based reasoning to infer events from low-level sensor data, (4) query translation from SOS format into SPARQL.

Trusted Perception Cycle

This demo helps in visualizing the perception cycle (abductive inference) and reputation values computed for weather stations over a period of six days. Various features inferred from raw sensor data using the perception cycle are depicted with different colors of the bars and height of the bar represents the reputation value of each weather station. The demo shows all the inferred features and the way in which the reputation computation converges. Main contributions include: (1) Development and formalization of perception cycle (2) Implementation of a reputation system which used beta-pdf distribution to compute trust values.

Real-time Feature Streams

Real Time Feature Streams focuses on reasoning over lower-level raw sensor data streams to detect higher-level abstractions called features (a concept that represents a real world entity like Blizzard, RainStorm etc) in real-time. The feature-streams are added to the Linked Open Data Cloud (LOD).Main contributions involve: (1) Integration of multiple, multimodal, heterogeneous low-level sensor data streams to generate high-level feature streams. (2) The summarization is across the thematic dimension involving multiple data streams and the use of background knowledge as opposed to summarizations of single streams across temporal dimension (like min,max,average etc).

Scooner users largely automatically generated background knowledge to support deeper insights and knowledge discovery from text. Knowledge base is used for semantic extraction. A semantic search and browsing is supported as iterative process involving ontology-guided exploration or trail-blazing that focuses on relationships, and not just entities. Current version shows how biologists in Human Performance and Cognition (HPCO) research can find insights from the corpus of all of 18+MM PubMed abstracts far better than using a PubMed search.

Doozer: Knowledge Extraction from Community-Generated Content

Doozer is an application that aims at generating or extracting a domain model from Wikipedia or other similarly structured knowledge sources. It takes as input an incomplete description of a domain, such as a query or list of seed concepts. Doozer then expands on these seeds to get related concepts, which are then again evaluated regarding their indicativeness of the domain. The output is an extended model that still focuses on the intended domain.

Keywords : Doozer, Knowledge extraction, domain model

Cuebee is a flexible, extensible application for querying the semantic web. It provides a friendly interface to guide users through the process of formulating complex queries. No technical knowledge of query languages or the semantic web is required. They key enabler of the query builder is the ontology schema. The schema provides the types and possible interconnections of data to guide the user in creating a query.

Knowledge-Aware Search

Knowledge-Aware Search is a hybrid approach to domain specific information retrieval that goes beyond ontology-driven query interpretation as well as beyond synonym-based query expansion used in Information Retrieval (IR). A knowledge-aware search platform is more amenable to domain specific searches involving complex information needs than general-purpose search frameworks.
