ReadLet: A Dataset for Oral, Visual and Tactile Text Reading Data of Early and Mature Readers
Marcello Ferro | Claudia Marzi | Andrea Nadalini | Loukia Taxitari | Alessandro Lento | Vito Pirrelli
Proceedings of the 2024 Joint International Conference on Computational Linguistics, Language Resources and Evaluation (LREC-COLING 2024)

The paper presents the design and construction of a time-stamped multimodal dataset for reading research, including multiple time-aligned temporal signals elicited with four experimental trials of connected text reading by both child and adult readers. We present the experimental protocols, as well as the data acquisition process and the post-processing phase of data annotation/augmentation. To evaluate the potential and usefulness of a time-aligned multimodal dataset for reading research, we present a few statistical analyses showing the correlation and complementarity of multimodal time-series of reading data, as well as some results of modelling adults’ reading data by integrating different modalities. The total dataset size amounts to about 2.5 GByte in compressed format.

Evaluating Hebbian Self-Organizing Memories for Lexical Representation and Access
Claudia Marzi | Marcello Ferro | Claudia Caudai | Vito Pirrelli
Proceedings of the Eighth International Conference on Language Resources and Evaluation (LREC'12)

The lexicon is the store of words in long-term memory. Any attempt at modelling lexical competence must take issues of string storage seriously. In the present contribution, we discuss a few desiderata that any biologically-inspired computational model of the mental lexicon has to meet, and detail a multi-task evaluation protocol for their assessment. The proposed protocol is applied to a novel computational architecture for lexical storage and acquisition, the """"Topological Temporal Hebbian SOMs"""" (T2HSOMs), which are grids of topologically organised memory nodes with dedicated sensitivity to time-bound sequences of letters. These maps can provide a rigorous and testable conceptual framework within which to provide a comprehensive, multi-task protocol for testing the performance of Hebbian self-organising memories, and a comprehensive picture of the complex dynamics between lexical processing and the acquisition of morphological structure.

Unsupervised Acquisition of Verb Subcategorization Frames from Shallow-Parsed Corpora

Proceedings of the Sixth International Conference on Language Resources and Evaluation (LREC'08)

In this paper, we reported experiments of unsupervised automatic acquisition of Italian and English verb subcategorization frames (SCFs) from general and domain corpora. The proposed technique operates on syntactically shallow-parsed corpora on the basis of a limited number of search heuristics not relying on any previous lexico-syntactic knowledge about SCFs. Although preliminary, reported results are in line with state-of-the-art lexical acquisition systems. The issue of whether verbs sharing similar SCFs distributions happen to share similar semantic properties as well was also explored by clustering verbs that share frames with the same distribution using the Minimum Description Length Principle (MDL). First experiments in this direction were carried out on Italian verbs with encouraging results.

Searching treebanks for functional constraints: cross-lingual experiments in grammatical relation assignment
Felice Dell’Orletta | Alessandro Lenci | Simonetta Montemagni | Vito Pirrelli
Proceedings of the Fifth International Conference on Language Resources and Evaluation (LREC’06)

The paper reports on a detailed quantitative analysis of distributional language data of both Italian and Czech, highlighting the relative contribution of a number of distributed grammatical factors to sentence-based identification of subjects and direct objects. The work is based on a Maximum Entropy model of stochastic resolution of grammatical conflicting constraints, and is demonstrably capable of putting explanatory theoretical accounts to the challenging test of an extensive, usage-based empirical verification.

Creation and Use of Lexicons and Ontologies for NL Interfaces to Databases
Roberto Bartolini | Caterina Caracciolo | Emiliano Giovanetti | Alessandro Lenci | Simone Marchi | Vito Pirrelli | Chiara Renso | Laura Spinsanti
Proceedings of the Fifth International Conference on Language Resources and Evaluation (LREC’06)

In this paper we present an original approach to natural language query interpretation which has been implemented withinthe FuLL (Fuzzy Logic and Language) Italian project of BC S.r.l. In particular, we discuss here the creation of linguisticand ontological resources, together with the exploitation of existing ones, for natural language-driven database access andretrieval. Both the database and the queries we experiment with are Italian, but the methodology we broach naturally extends to other languages.
