Document Clustering

The project e-ŠNUNNA analyzes a corpus of letters of the old-Babylonian Kingdom of EŠNUNNA, by exploiting Document Clustering, in sinergy with other e-tools.
Text Clustering is a data mining technique, which identifies set of documents, sharing common features (i.e., the same topic). Document in the same cluster are similar or highly-related to each other than texts belonging to different clusters.
In the e-ŠNUNNA Project one of the aims is to discover homogeneous groups and hidden relations in the data, to support scholars in their assyriological studies. For this purpose, ENEA developed a data mining tool, called ASTEC (ASsyriology Text Clustering), which offers a set of clustering algorithms and features, analyzes and discovers homogenous groups of transliterated and lemmatized.
The selected texts belong to a collections of 51 tablets, first transliterated by Albrecht Goetze in "Fifty Old Babylonian Letter from Harmal" (Sumer 14), 1958, pp. 3-78, and now slightly reviewed. These letters offer important elements for a study of the E-ŠNUNNA old Babylonian grammar.
After TalTaC2 text processing and grammatical tagging, texts were lemmatized and then TalTaC2 reconstructed all fragments by lemmas, following the original sequence of words.

Corpus Characteristics
The lemmatized Corpus is composed by 2741 word form (token) and has a vocabulary of 500 word types. It shows a lexical richness index of 18% and 50% of hapax.
Senders and Receivers were explicitly identified, and this will be useful for further prosopographic and geographic analysis and studies (see TALTAC screenshot).
With respect to general corpora, in TaLTaC2, these texts shows peculiarities in the text mining phase, such as:
- punctuation is lacking;
- word boundaries are marked only by space and carriage return (punctuation marks were not assumed as separator, due to their different function in transliteration methodologies in Assyriology);
- Akkadian personal names have been written in lower case;
- Sumerograms have been written in small caps;
- e-texts with UNICODE characters required a limited intervention of simplification (see text encoding ).
