This study focuses on the investigation of certain bronze adornment objects from the First Iron Age (the so-called middle Hallstatt period), dating to the ninth–eighth c. BC. These objects are part of a bronze and iron hoard (labeled Cx 116) discovered in the present Romanian territory, at Tărtăria–Podu Tărtăriei vest archaeological site, in Alba County. Along with a second hoard of bronze and iron objects, this represents a unique discovery for the present Romanian territory, namely, for the

The objects, approximately 450 bronze and iron objects—weapons, tools, adornments, and harnesses—were found in the two hoards, in the Southern ditch, which outlines the archaeological site. Digital radiography has been used to assess the physical state of the objects and to identify potential specific craftsmanship details. It showed a fairly good preservation status, with incipient corrosion processes located in the core of some of the objects and some specific traces of the crafting process and subsequent mechanical defects were highlighted. The relatively good state of preservation of the objects can result from the fact that they had been protected from the humid environment by the ceramic vessel they were placed in. XRF and LIBS were used to identify the materials and to stratigraphically evaluate the objects. XRF scanned the surface of the objects, revealing elements related to both the raw material—a copper alloy with tin and lead, together with trace elements related to the specific mining location of the ores, and the depositional environment of the objects–such as iron. LIBS allowed a more in-depth stratigraphic analysis, which indicated a higher copper ratio—compared to iron—as the kinetic series advance, fact that sustains the idea that the major iron input was coming from the depositional environment. Both XRF and LIBS results were consistent with high elemental variability, probably due to the nature of the original material and the influence of the deposition soil conditions.

Concept extraction from legal cases

Marie-Francine Moens, Roxana Angheluta
2003 Proceedings of the 9th international conference on Artificial intelligence and law - ICAIL '03  
Effective retrieval of court decisions is important. Automatically identifying legal concepts in the decision texts would be very helpful. In this paper we investigate how a statistics for hypothesis testing, i.e., the likelihood ratio, can help in this task. We describe how this statistic can be used for detecting important multi-term phrases in the case texts, how it can be used to find correlated terms, and how it is a means for feature or topic signature selection in automated case

An Unsupervised Language Independent Method of Name Discrimination Using Second Order Co-occurrence Features [chapter]

2006 Lecture Notes in Computer Science  
Previous work by Pedersen, Purandare and Kulkarni (2005) has resulted in an unsupervised method of name discrimination that represents the context in which an ambiguous name occurs using second order co-occurrence features. These contexts are then clustered in order to identify which are associated with different underlying named entities. It also extracts descriptive and discriminating bigrams from each of the discovered clusters in order to serve as identifying labels. These methods have been

In this paper we apply this methodology in exactly the same way to Bulgarian, English, Romanian, and Spanish corpora. We find that it attains discrimination accuracy that is consistently well above that of a majority classifier, thus providing support for the hypothesis that the method is language independent.

"Multi- and inter- disciplinary approaches in the scientific documentation and monitoring of cultural heritage assets "

This paper synthesizes several aspects of the trends of the multi-and inter-disciplinary strategies regarding both research and applications in the scientific documentation and conservation status monitoring of cultural heritage assets such as museum items, monuments, archaeological sites or even larger cultural landscapes, using modern technology. A comprehensive understanding of all physico-chemical, natural, social, and historical factors that had or still have damaging effects on the

All these factors are interrelated and cannot be separated nor can a preventive conservation strategy be successfully implemented by considering just one aspect of the problem. Along this line this paper presents our own solutions and their evolution during time. Multi-disciplinary projects in collaboration with research groups coming from different disciplines (natural studies or social and humanities areas) will be discussed. E-learning courses for joint groups of students coming from different disciplines will also be described together with online platforms with customized databases for the management and dissemination of the scientific data resulted from the project activities.

The software employs the client server architecture for device control and feedback data. The user interface is built for the purpose of interaction, using the LabView web-server technology. The device is operated from any distance, in real time, through a embedded HTML web page.

Improving name discrimination

Ted Pedersen, Anagha Kulkarni, Zornitsa Kozareva, Roxana Angheluta, Thamar Solorio
2006 Proceedings of the International Workshop on Cross-Language Knowledge Induction - CrossLangInduction '06   unpublished
This paper describes a method of discriminating ambiguous names that relies upon features found in corpora of a more abundant language. In particular, we discriminate ambiguous names in Bulgarian, Romanian, and Spanish corpora using information derived from much larger quantities of English data. We also mix together occurrences of the ambiguous name found in English with the occurrences of the name in the language in which we are trying to discriminate. We refer to this as a language salad,

Semantic case role detection for information extraction

Rik De Busser, Roxana Angheluta, Marie-Francine Moens
2002 Proceedings of the 19th international conference on Computational linguistics -   unpublished
If information extraction wants to make its results more accurate, it will have to resort increasingly to a coherent implementation of natural language semantics. In this paper, we will focus on the extraction of semantic case roles from texts. After setting the essential theoretical framework, we will argue that it is possible to detect case roles on the basis of morphosyntactic and lexical surface phenomena. We will give a concise overview of our methodology and of a preliminary test that seems to confirm our hypotheses.
