standOff, and the article is at its publisher via the link below. When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.| second reading | alternatives | an independent re-reading of a facet, recorded whether or not it agrees |

'experienced operators tended to make similar judgements during the manual curation process, but Quotation withheld ... we therefore recommend that these [quantitative criteria] be used, rather than human judgements.'

'TEMPLATE-MATCHING ALGORITHMS HAVE SOLVED THIS PROBLEM IN THE CASE OF IN VITRO RETINAL ARRAY DATA, BUT THESE DATA ARE MUCH LESS NOISY THAN IN VIVO BRAIN RECORDINGS.'

The sentence is in the paper at the link above. EVIDENCE CORRECTED: RE-GROUNDED. The old span was about operator consistency. This sentence names both as the two outcomes of one decision - the operator '…WELL-ISOLATED neuron, OR rejects it as MULTIUNIT ACTIVITY…' - so the contrast is a forced choice rather than an observed difference. — strength of the relation: 1 · note: the boundary the operator study found to be operator-dependent also in: well-isolated · multiunit activity | concept_edges[5] | 0.85 | the tagger's words |

The convention is from=part, to=whole - 'vertex --part-of--> network'. NO separate quote for the relation: the span's composition cue is 'involves', which is not in CONTAINER_FIRST, and its only other attestation in the corpus (Pickering2008) is fenced.

What was deliberately not tagged, and why, is recorded per paper by the tagger. Where a paper has no such record, this page says so rather than implying that nothing was declined.
