Source-derived summary

In computer science, a left corner parser is a type of chart parser used for parsing context-free grammars. It combines the top-down and bottom-up approaches of parsing. The name derives from the use of the left corner of the grammar's production rules.

An early description of a left corner parser is "A Syntax-Oriented Translator" by Peter Zilahy Ingerman.

Editorial summary

This brief starts where responsible research should: with the source description of “Left corner parser” as type of chart parser. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—2002, 2017—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Left, corner and parser can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as type of chart parser. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Nov 29, 2024. The linked authority identifier is Q6516945. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2002 and 2017.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
