| Main enrichment/annotation layer | Corpus compilation | Entity annotation for people, places, and organizations | Processed and unprocessed text, NER, geocoding, entity sentiment analysis, and network-analysis outputs |
| Preprocessing/curation profile | No enrichment-oriented preprocessing pipeline | Entity annotation added to the core corpus | Explicit preprocessing pipeline: tokenization; removal of numbers, dates, very short tokens, and isolated special characters; correction of split words; selective retention of punctuation and stopwords |
| Main contribution relative to previous version | Establishes the reusable core corpus | Adds structured entity annotation to the original corpus | Expands corpus size, titles, and time span, and adds contextual enrichment layers |
