An Evaluation Exercise for Word Alignment
Date: May 2003
Creator: Mihalcea, Rada, 1974- & Pedersen, Ted
Description: This paper discusses an evaluation exercise for word alignment. Abstract: This paper presents the task definition, resources, participating systems, and comparative results for the shared task on word alignment, which was organized as part of the HLT/NAACL 2003 Workshop on Building and Using Parallel Texts. The shared task included Romanian-English and English-French sub-tasks, and drew the participation of seven teams from around the world.

Evaluation Results of an E and ET Education Forum
Date: 2011
Creator: Ramos, Miguel; Chapman, Lauren; Cannady, Mac & Barbieri, Enrique
Description: This article discusses evaluation results of an Engineering (E) and Engineering Technology (ET) education forum. Abstract: Under a two-year Department of Education FIPSE grant, the College of Technology at the University of Houston hosted a two-day forum in spring 2010 to explore a variety of issues related to E and ET education. A central focus to these discussions revolved around whether E and ET exist as separate fields or whether there was value in thinking about them as part of a continuum. The CDIO (conceive-design-implement-operate) model was used as a framework for thinking about these two knowledge areas as facets of an overarching engineering profession, where the majority of E and ET graduates flow to the middle of CDIO and engage in "design-implement" tasks within three to five years after graduation. Several implications of a continuum-based framework for engineering education were debated within the context of two alternative curricular approaches. The first approach envisions a two-year curriculum in which E and ET students enroll in a set of common technical core courses. At the end of the second year, students would make a well-educated decision to become either engineering or engineering technology majors, subsequently completing a BS degree. The second ...

Exploiting Agreement and Disagreement of Human Annotators for Word Sense Disambiguation
Date: September 2003
Creator: Chklovski, Timothy A. (Timothy Anatolievich), 1977 & Mihalcea, Rada, 1974-
Description: This paper discusses word sense disambiguation. Abstract: It is generally agreed that the success of a Word Sense Disambiguation (WSD) system depends, in large, on having enough sense annotated data available at hand, and a well-motivated sense inventory into which the disambiguations are made. The authors report a Web-based approach to (1) constructing large sense tagged corpora by exploiting agreement of Web users who contribute word sense annotation, and (2) deriving a coarse-grained sense inventory from a fine-grained inventory by exploiting disagreements of independent contributors about word senses. The authors investigate the quantity and quality of the sense tagged data collected with this approach over the past year. The authors present and evaluate an automatic clustering algorithm able to derive sense clusters that compare well with manually constructed clusters.

Explorations in Automatic Book Summarization
Date: June 2007
Creator: Ceylan, Hakan & Mihalcea, Rada, 1974-
Description: This paper discusses explorations in automatic book summarization. Abstract: Most of the text summarization research carried out to date has been concerned with the summarization of short documents (e.g., news stories, technical reports), and very little work if any has been done on the summarization of very long documents. In this paper, we try to address this gap and explore the problem of book summarization. We introduce a new data set specifically designed for the evaluation of systems for book summarization, and describe summarization techniques that explicitly account for the length of the documents.

eXtended WordNet: progress report
Date: June 2001
Creator: Mihalcea, Rada, 1974- & Moldovan, Dan I.
Description: This paper discusses eXtended WordNet. Abstract: eXtended WordNet (XWN), a morphologically and semantically enhanced version of the WordNet dictionary, is currently build at SMU. There are several phases in the XWN project. This paper focuses on the semantic disambiguation stage of this project, and the preprocessing required by this stage.

FALCON: Boosting Knowledge for Answer Engines
Date: November 2000
Creator: Harabagiu, Sanda M.; Moldovan, Dan I.; Paşca, Marius. 1974-; Mihalcea, Rada, 1974-; Surdeanu, Mihai; Bunescu, Răzvan et al
Description: This paper discusses FALCON. Abstract: This paper presents the features of FALCON, an answer engine that integrates different forms of syntactic, semantic and pragmatic knowledge for the goal of achieving better performance. The answer engine handles question reformulations, finds the expected answer type from a large hierarchy that incorporates the WordNet semantic net and extracts answers after performing unifications on the semantic forms of the question and its candidate answers. To rule out erroneous answers, it provides justification option, implemented as an abductive proof. In TREC-9, FALCON generated a score of 58% for short answers and 76% for long answers.

Finding Semantic Associations on Express Lane
Date: May 2004
Creator: Nastase, Vivi & Mihalcea, Rada, 1974-
Description: This paper introduces a new codification scheme for efficient computation of measures in semantic networks. The scheme is particularly useful for fast computation of semantic associations between words and implementation of an informational retrieval operator for efficient search in semantic spaces. Other applications may also be possible.

Flexible Allocation of Capacity in Multi-Cell CDMA Networks
Date: July 1999
Creator: Akl, Robert G.; Hegde, Manju V.; Naraghi-Pour, Mort & Min, Paul S.
Description: This presentation discusses flexible allocation of capacity in multi-cell CDMA networks. The effect of reverse power levels on the capacity of a code-division multiple-access (CDMA) cellular network is evaluated. The inter-cell and intra-cell interferences of every cell on every other cell are first calculated for a given network topology. Based on this, the nominal power of users is increased by a factor the authors call the Power Compensation Factor (PCF) which enables small cells to overcome the excessive interference from adjacent large cells.

Framework for Design Validation of Security Architectures
Date: November 17, 2008
Creator: Dwoskin, Jeffrey Scott, 1980-; Gomathisankaran, Mahadevan & Lee, Ruby Bei-Loh
Description: This technical report discusses a framework for design validation of security architectures. Abstract: New security architectures are difficult to prototype and test. They require interactions between hardware, operating systems, and applications, making them hard to simulate and monitor. The authors have designed and prototyped a testing framework using a virtualization platform which emulates the behavior of new hardware security architecture in the virtual CPU, and performs a wide range of hardware and software attacks on the system under test. The authors' testing framework significantly speeds up development of the testing environment and infrastructure, and provides APIs for launching attacks and monitoring the effects of an attack on the hardware and software layers, which is especially convenient during the design and validation phases for new hardware-software architectural solutions. The authors have used this testing framework to test the trust chain of the SP architecture as an example.
