  <description><![CDATA[Pointwise mutual information (PMI) is a widely used word similarity measure, but it lacks a clear explanation of how it works. We explore how PMI differs from distributional similarity, and we introduce a novel metric, PMImax, that augments PMI with information about a word's number of senses. The coefficients of PMImax are determined empirically by maximizing a utility function based on the performance of automatic thesaurus generation. We show that it outperforms traditional PMI in the appl...]]></description>

  <description><![CDATA[Cyber physical systems (CPS) and cyber infrastructure are a key elements of the national infrastructure, and securing them is of vital importance to national security. There is ample evidence that these systems are vulnerable to disruption and damage due to natural disasters social crises, and terrorism.  CPS applications are becoming more widespread, ranging from healthcare patient monitoring systems to autonomous vehicles to integrated electrical power grids.  often the new application doma...]]></description>

  <description><![CDATA[The production management system used by most manufacturers today consists of disconnected planning and execution processes and lacks the support for interoperability and collaboration needed for enterprise-wide integration. This situation often prevents the manufacturer from fully exploring market opportunities in a timely fashion. To address this problem, we are exploring an agent-based approach to intelligent enterprise integration. In this approach, a set of agents with specialized expert...]]></description>

  <link>http://ebiquity.umbc.edu/paper/html/id/574/The-Effect-of-Perceptual-Structure-on-Multimodal-Speech-Recognition-Interfaces</link>
  <description><![CDATA[A framework of complementary behavior has been proposed which maintains that direct
manipulation and speech interfaces have reciprocal strengths and weaknesses. This suggests that
user interface performance and acceptance may increase by adopting a multimodal approach that
combines speech and direct manipulation. This effort examined the hypothesis that the speed,
accuracy, and acceptance of multimodal speech and direct manipulation interfaces will increase
when the modalities match the ...]]></description>

  <description><![CDATA[Ontology alignment describes a process of mapping ontological concepts, classes and attributes between different ontologies providing a way to achieve interoperability. While there has been considerable research in this area, most approaches that rely upon the alignment of attributes use labelbased string comparisons of property names. The ability to process opaque or non-interpreted attribute names is a necessary component of attribute alignment. We describe a new attribute alignment approac...]]></description>

  <description><![CDATA[We describe our ongoing work on using social media as a platform for citizen science. Building on our previous work of facilitating citizen science observations, and using RDF to integrate them with existing biodiversity knowledge, we are currently building Facebook Apps that will enable the reporting of observations, as well as the browsing and tagging of existing observations.  The tagging capability serves two main purposes. First, it permits (and, we hope, encourages) multi-stage crowdsou...]]></description>

  <description><![CDATA[One of the key challenges in designing expert systems is a credible representation of uncertainty and partial belief. During the past decade, a number of rule-based belief languages were proposed and implemented in applied systems.Due to their quasi-probabilistic nature, the external validity of these languages is an open question. This paper discusses the theory of belief revision in expert systems through a canonical belief calculus model which is invariant across different languages. A met...]]></description>

  <description><![CDATA[Memo functions and memoization are well-known concepts in AI programming. They have been discussed since the sixties and are often used as examples in introductory programming texts. However, the automation of memoization as a practical software engineering tool for AI systems has not received a detailed treatment. This paper describes how automatic memoization can be made viable on a large scale. It points out advantages and uses of automatic memoization not previously described, identifies ...]]></description>

  <description><![CDATA[Work in progress on JETS, the successor to PLANES, is described. JETS is a natural language question answering system that is intended to interface users to a large relational data base. The architecture is designed to extend the conceptual coverage of JETS to better meet the conversational and data base usage requirements of users. The implementation of JETS is designed to gain a high degree of closure over concept manipulation, contributing to a solution to the problems of perspicuity and s...]]></description>

  <description><![CDATA[One of the unique advantages brought by the Semantic Web
is that semantic web languages, such as RDF and OWL, offer a small but expressive set of common ontological constructs for agents to share knowledge on the Web. Instead of
hard coding knowledge inside intelligent agents, the semantic web enables agents to publish and consume knowledge
explicitly stored in web documents. The utility of the Semantic Web can be evaluated from three equally important
aspects: availability – is there e...]]></description>
