Franco Niccolucci: Example of an EOSCpilot Science Demonstrator - TextCrowd
- 1. Franco Niccolucci & Achille Felicetti (PIN, University of Florence, Italy) EOSC-hub Week 2018 Malaga, 16/4/2018
- 2. EOSCpilot is a project funded by the EC H2020 programme Domain: Archaeology Goal: semantic enrichment of texts Archaeological documentation largely based on texts ◦ Excavation diaries, reports, surveys, grey literature ◦ Literary/historical sources. research articles, monographs … ◦ Huge number of small (<100Kb) files in different languages Registry of 2,000,000 archaeological datasets (70% texts) in ARIADNE ARIADNE’s data infrastructure popular among archaeologists ◦ ARIADNE users in 2016: 25-30% of the European research community ◦ Strong support by Professional associations (EAA, EAC) & national archaeological/cultural heritage authorities National research institutions (CNR, CNRS, CAS, ÖAW, KNAW, BAS, ATHENA RC, FORTH) International recognition (USA, Mexico, Japan, Argentina) Needed for cloud-based data infrastructure to be developed in ARIADNEplus ◦ Deeper integration between texts, databases, GIS etc. ◦ Advanced services & VREs for data-centric archaeological research 2
- 3. EOSCpilot is a project funded by the EC H2020 programme NLP & NER OS engine Syntactic rules (tailored to specific writing style) Texts stating facts, not stories ◦ Data fuzziness, provenance, reliability, reasoning Domain ontology: CIDOC CRM (ISO 21127:2006) ◦ ... and not TEI Terminology ◦ Specialized vocabularies Terra sigillata is not just “sealed earth” ◦ Gazetteers for modern (Geonames) and ancient (Pleiades) place names Málaga (modern) vs Màlaka (Phoenician) vs Màlaca (Roman) ◦ Named time period management Bronze Age (∼ 3200-600 BC), Recent Orientalizing Period (∼ 630-570 BC)
- 4. EOSCpilot is a project funded by the EC H2020 programme Modular framework based on GATE toolchain: https://gate.ac.uk ◦ Advanced stemming/lemmatization components OpenNLP (https://opennlp.apache.org) : sentence segmentation and part of speech (POS) tagging OpeNER (http://www.opener-project.eu) neuronal network for advanced named entities recognition (NER), developed in OpeNER FP7 project ◦ Machine learning framework for auto education Annotated corpus required Ontology: CRMarcheo (CRM extension for archaeology) Vocabularies, gazetteers and terminological tools ◦ ICCD vocabularies for Italian archaeology, augmented with term lists created on purpose ◦ Geonames (modern places), Pleiades (historical places) ◦ Timespan and named period component based on PeriodO 4
- 5. EOSCpilot is a project funded by the EC H2020 programme TextCrowd detects: ◦ Artefacts ◦ Colours ◦ Materials ◦ Time periods ◦ Persons ◦ Places ◦ Sites ◦ Time spans ◦ Techniques Target output formats: ◦ Textual documents automatically annotated and enriched ◦ CIDOC CRM semantic triples (RDF) 5
- 6. EOSCpilot is a project funded by the EC H2020 programme No annotated text corpora available in Italian to be used as training data for machine learning algorithms ◦ Manual annotation of 400 pages of Italian archaeology reports (< 1 Person-Month) Preparation and adaptation of vocabularies Availability of user-friendly cloud-based environments and of necessary tools, to migrate standalone prototype to cloud ◦ Several cloud solutions tested in early development, limited support provided except in D4Science ◦ Implementation in D4Science infrastructure, but portable to other cloud services if support and required modules available Authentication and Authorization ◦ No access control to metadata/data implemented so far ◦ Demonstrator focused on freely accessible textual documents ◦ Fasti Online used (http://www.fastionline.org) Open Access collection of archaeological reports 6
- 7. EOSCpilot is a project funded by the EC H2020 programme Operated and maintained by CNR-ISTI on the D4Science platform https://www.d4science.org Modular engine based on GATE toolchain + OpenNLP-OpeNER modules, natively provided by D4Science Web-based user interface for ◦ User and access management ◦ Cloud storage (private and shared files) ◦ Results available for other Virtual Research Environments (VRE) within D4Science Released for open use, for tests & comments No fancy interface produced, also to adapt to any Look-and-Feel 7
- 8. EOSCpilot is a project funded by the EC H2020 programme Machine-readable results: RDF encoding produced Human-readable results: color-encoded text (for testing) Interoperability of extracted knowledge ◦ Semantic information in CRM format: full integration and interoperability with other archaeological semantic data (to be fully implemented in ARIADNEplus) Supporting FAIR Principles implementation ◦ Metadata to be stored in various registries for easy findability and accessibility ◦ Results ready to be reused within the same environment or consumed by other services and/or in different scenarios 8
- 9. EOSCpilot is a project funded by the EC H2020 programme TEXTCROWD has shown to be useful for its main purpose: to demonstrate the importance and usefulness of EOSC for scientific research in the cultural heritage domain Adoption by other research teams in the EOSCpilot framework ◦ Integration of TEXTCROWD with new VisualMedia Demonstrator: a service for sharing and visualizing visual media files on the web - automatic metadata extraction from controlled lists or textual documents for 2D and 3D models Testing on real use cases in progress ◦ Open Access papers of the Italian Journal Archeologia e Calcolatori, ongoing Clean visualization Language extension ◦ English, Dutch: from standalone to cloud-based (annotated corpora available) ◦ French, Spanish, German: new from scratch (annotated corpora to be prepared) ◦ Other EU languages: OpeNER extension required Additional work required to suit it to everyday use – but not too much 9
