We consider the problem of extracting text instances of predefined categories (e.g. city and person) from the Web. Instances of a category may be scattered across thousands of independent sources in many different formats with potential noises, which makes open-domain information extraction a challenging problem. Learning syntactic rules like “cities such as _” or “_

Archimedes: Efficient Query Processing over Probabilistic Knowledge Bases
Xiaofeng Zhou Comment Closed publications, research directions
We present the ARCHIMEDES system for efficient query processing over probabilistic knowledge bases. We design ARCHIMEDES for knowledge bases containing incomplete and uncertain information due to limitations of information sources and human knowledge. Answering queries over these knowledge bases requires efficient probabilistic inference. In this paper, we describe ARCHIMEDES’s efficient knowledge expansion and query-driven inference over UDA-GIST, an

Extracting Visual Knowledge from the Web with Multimodal Learning
Dihong Gong Comment Closed publications, research directions
We consider the problem of automatically extracting visual objects from web images. Despite the extraordinary advancement in deep learning, visual object detection remains a challenging task. To overcome the deficiency of pure visual techniques, we propose to make use of meta text surrounding images on the Web for enhanced detection accuracy. In this work we present

Interactive Inference for Information Extraction
sean Comment Closed Uncategorized
Introduction In order to keep up with the enormous pace of data being produced on the web, we need automatic methods for converting it into a more structured form for analyzing and querying. For text data this amounts to generating labels which describe the underlying semantic concept and is known as Information Extraction (IE). Examples

SigmaKB VLDB16 Demo System and TAC KBP Slot Filling Validation 2016
Miguel Rodriguez Comment Closed Uncategorized
Miguel Rodriguez The amount of information available on the web has motivated a number of efforts in creating large-scale knowledge bases (KBs), each with their own methods of automatically extracting relevant information from unstructured text. Despite sharing the same data model, each project is unique, displaying their own strengths and weaknesses related to the size

The ArchimedesOne Knowledge Base System
yang Comment Closed publications, research directions
Yang Chen, Xiaofeng Zhou Recent development in information extraction and data management systems arouses elevating efforts in constructing large knowledge bases (KBs). These knowledge bases store information in a structured format, facilitating efficient processing and querying. Examples of these knowledge bases include DBpedia, DeepDive, Freebase, Google Knowledge Graph, Knowledge Vault, NELL, OpenIE, ProBase, ProbKB, and

NIST 2015 Knowledge Base Population – Ensemble
Miguel Rodriguez Comment Closed NIST and open eval, research directions
Miguel Rodriguez The Text Analysis Conference (TAC) is a series of evaluation workshops organized by NIST to encourage research in Natural Language Processing and related applications. TAC is focused on Knowledge Base Population (KBP), automated systems that discover information about entities found in a large corpus and incorporate them into a knowledge base. The TAC-KBP evaluation is composed

NIST 2015 Pre-Pilot Data Science Evaluation
Dihong Gong Comment Closed courses, NIST and open eval, research directions
Dihong Gong and Daisy Zhe Wang We participated in the 2015 Pre-Pilot Data Science Evaluation organized by the National Institute of Standards and Technology (NIST). The primary goal of the pre-pilot evaluation is to develop and exercise the evaluation process in the context of data science. The evaluation consists of four tasks including data cleaning,

SMART Electronic Discovery: System Evaluation
Clint P. George Comment Closed research directions
Clint P. George This is an extension to our earlier post, SMART Electronic Discovery (SMARTeR), which describes a framework for electronic discovery (e-discovery). Discovery is a pre-trial procedure in a lawsuit or legal investigation in which each party can obtain evidence from other parties (typically via a request for production) according to the laws of civil procedure in the

Multimodal Ensemble Fusion for Disambiguation and Retrieval
Yang Peng Comment Closed publications, research directions
Yang Peng Huge amount of multimedia data is generated on the Internet everyday. In order to utilize multimodal data, researchers have developed a lot of multimodal machine learning models to integrate data of multiple modailities, including text, images, audios and videos. In the multimedia analysis community, multimodal fusion is greatly employed for various multimedia analysis
