We report work 1 in progress on adding affect-detection to an existing program for virtual dramatic improvisation, monitored by a human director. To partially automate the directors’ functions, we have partially implemented the detection of emotions, etc. in users’ text input, by means of pattern-matching, robust parsing and some semantic analysis. The work also involves basic research into how...

Research on the history of words has led to remarkable insights about language and also about the history of human civilization more generally. This paper presents the Etymological Wordnet, the first database that aims at making word origin information available as a large, machine-readable network of words in many languages. The information in this resource is obtained from Wiktionary. Extract...

Over the past few years the attacks on Software systems is increasing at an astonishing rate resulting in high revenue losses. Hence, Cyber/Digital forensics plays an important role by providing methods to acquire, asses, interpret, and use digital evidence to fetch conclusive details of cyber crime behavior. Recent trend in cyber crimes is the use of Anti-Forensic attacks to thwart the process...

Substitution operations on tree series are at the basis of systems of equations (over tree series) and tree series transducers. Tree series transducers seem to be an interesting transformation device in syntactic pattern matching. In this contribution, it is shown that o-substitution preserves recognizable tree series provided that the target tree series is linear and the semiring is idempotent...

Once referred to as the missing circuit component, memristor has come long way across to be recognized and taken as important to future circuit designs. The memristor due to its ability to memorize the state, switch between different resistance level, smaller size and low leakage currents makes it useful for a wide range of intelligent memory and computing applications. This overview paper high...

We show that, using the L 1 metric, the minimum Hausdor distance under translation between two point sets of cardinality n in d-dimensional space can be computed in time O(n (4d 2)=3 log 2 n) for 3 < d 8, and in time O(n 5d=4 log 2 n) for any d > 8. Thus we improve the previous time bound of O(n 2d 2 log 2 n) due to Chew and Kedem. For d = 3 we obtain a better result of O(n 3 log 2 n) time by e...

This paper describes link discovery technology that is designed to detect threat activities by extracting and piecing together transactional evidence from massive datasets that are composed mostly of noise and clutter. The approach is an integration of several innovative component technologies, including partial pattern matching, hypothesis evaluation and hypothesis merging.
