Analysis of Information Features in Natural Language Queries for Music Information Retrieval: Use Patterns and Accuracy
… be made: (i) incorporating user context in test queries, (ii) employing terms familiar to users in evaluation tasks, and (iii) combining multiple task results are recommended. Information about related multimedia works and applying attributive/referential readings of descriptions in IR may also …

A natural language interface for querying graph databases
… no understanding of database schemes and query languages. Providing a tool that translates natural language queries into structured queries allows people without this technical knowledge or specific domain expertise to retrieve information that was previously inaccessible. Many existing natural …

The audio-graphical interface to a personal integrated telecommunications system
… messages over the telephone by voice using natural language queries, or with the telephone keypad. Electronic mail messages and system status are transmitted by a text-to-speech synthesizer. Local access is provided by a touch sensitive screen and color raster display. Text and digitized …

Identifying Healthcare Access and Enhancing Geospatial Analysis with Generative AI
… fine-tunes OpenAI's GPT-4o-mini model to convert natural language queries into executable Python code for geospatial analysis. Trained on over 600 geospatial prompt-completion pairs using Virginia health data, the model achieves an 89.7% accuracy rate, improving significantly over the baseline. It …

Towards Generalizable Information Extraction with Limited Supervision
… challenges when attempting to generalize to new languages, domains, or types, particularly in the absence of sufficient annotations. Current methods fall short in effectively addressing information extraction (IE) under limited supervision. In this dissertation, we approach information extraction …

Deep learning for spoken dialogue systems : application to nutrition
… Siri, Cortana, and Alexa must translate a user's natural language query into a semantic representation that the back-end can then use to retrieve information from relevant data sources. For example, answering a user's question about the number of calories in a food requires querying a database …

Advanced Computer Vision for Smart Retail: From Anomaly Detection to Fine-grained Product Classification
… and segmentation of products based on natural language descriptions. By combining open-vocabulary object detection with large language model reasoning, our approach addresses the unique challenges of dense product arrangements and fine-grained distinctions in complex retail scenes …

Uncertainty-Aware Knowledge Graph Retrieval Methods and Their Use in LLM Question-Answering
… generating accurate, interpretable responses to natural language queries posed over structured, graph-based datasets. Recent approaches to KGQA involve reducing the knowledge graph (KG) to a relevant subgraph, which is then encoded in natural language as a series of triples (subject, predicate, …

On the Provenance of Software Systems: Automating Software Traceability with Knowledge Graph and Large Language Model Synergy
… these are typically informal, heavy with natural language, and lack structured explainability. This work proposes that each artifact should be attended by a machine-readable, human-interpretable, extensible provenance record, implemented in the form of a knowledge graph, backed by …

Human-centered Ambient Artificial Intelligence In Smart Buildings
… of smart buildings. Second, a large language model-enhanced Building Energy Management (BEM) AI agent was studied as an integration of perception, reasoning, and action modules. Evaluated on a proposed benchmark comprising 120 natural-language queries across four residential datasets, …

A Framework for Semantic Enterprise Transformations
… transformation query such that various forms of queries can be submitted and semantically transformed without changes to the underlying traversal algorithms. The thesis demonstrates two scenarios. The first is a natural language scenario (Chapter 6), and the second is an event stream scenario. In …
