A Semantic Parsing Task is a semantic NLU task that involves parsing a variety of unstructured data items, such as text item, source code, and DNA, into a formal semantic representation.
- Context:
- input: an Unstructured Data Item such as text item, source code, or DNA sequence.
- output: a Semantic Model in a semantic representation language such as a logical form, a database query, or an abstract syntax tree.
- Performance Metrics: Verifiability, Unambiguousness, Canonical Form, Inference, Expressiveness.
- It can range from being a Natural Language Semantic Parsing Task to a Source Code Semantic Parsing Task to a Genomic Data Semantic Parsing Task.
- It can vary in depth from Shallow Semantic Parsing Tasks like keyword extraction to Deep Semantic Parsing Tasks like full discourse analysis.
- It can be solved using a Semantic Parsing System employing various semantic parsing algorithms.
- It can support diverse NLP Applications by ensuring logical fidelity in the outputs, crucial for applications where precision is critical, such as legal or technical domains.

- Example(s):
- a Natural Language Semantic Parsing Task that converts natural language instructions into database queries, such as transforming an ATIS (Air Travel Information System) query into an SQL statement for flight information retrieval.
- a Source Code Semantic Parsing Task that transforms code snippets into a structured format that elucidates underlying programming actions and logic, aiding in software development and debugging processes.
- a Genomic Data Semantic Parsing Task where sequences of DNA are parsed into annotated structures that detail gene functions and interactions, facilitating advanced genetic research and applications.
- a voice command like "Set an alarm for 7 am tomorrow" parsed into an actionable command for a smart device.
- a legal document analysis where complex contract clauses are parsed into structured representations that highlight key obligations and rights for faster legal reviews and compliance assessments.
- ...
- Counter-Example(s):
- Syntactic Language Parsing Tasks, which solely analyze the grammatical structure of sentences without interpreting their meaning.
- Semantic Annotation Tasks, which involve adding metadata to text but do not convert it into a formal semantic representation.
- Writing Tasks, where the primary goal is the creation of text, not its interpretation or structural transformation.

- Semantic parsing is the task of converting a natural language utterance to a logical form: a machine-understandable representation of its meaning. Semantic parsing can thus be understood as extracting the precise meaning of an utterance. Applications of semantic parsing include machine translation, [1] question answering,[2][3] ontology induction, [4] automated reasoning, [5] and code generation. The phrase was first used in the 1970s by Yorick Wilks as the basis for machine translation programs working with only semantic representations. [6] Semantic parsing is one of the important tasks in computational linguistics and natural language processing. Semantic parsing maps text to formal meaning representations. This contrasts with semantic role labeling and other
forms of shallow semantic processing, which do
not aim to produce complete formal meanings. [7]
In computer vision, semantic parsing is a process of segmentation for 3D objects. [8] [9] Here, we have attached a system architecture for Semantic Parser to understand more briefly. In this picture it represent a basic architecture of semantic parsing, where the whole process has multiple steps like Token Analyzer takes input from input sentence and generate token, Syntactic Analyzer generate parse tree, and with the help of set of rules it generate the semantic meaning of a sentence.

- Verifiability: With the representation scheme, it must be possible to compare (or match) the meaning of a sentence against the knowledge base.
- Unambiguousness: linguistic input may have several legitimate interpretations. A desired meaning representation should have the ability to tell which are more likely or unlikely
- Canonical form: It is desired that sentences with the same meaning should be assigned the same representation
- Inference: Inference refers to a system’s ability to draw valid conclusions based on the meaning representation ofinput and/or its store of knowledge
- Expressiveness: The expressiveness of a meaning representation language is a measure of the various meanings it candescribe. In principle, there is a very wide range of input and knowledge base. We want a meaning representation method that canaccurately represent any semantic natural language sentences.
