The data presented in Table 2 elucidates that the semantic congruence between sentence pairs primarily resides within the 80–90% range, totaling 5,507 such instances. Moreover, the pairs of sentences with a semantic similarity exceeding 80% (within the 80–100% range) are counted as 6,927 pairs, approximately constituting 78% of the total amount of sentence pairs. This forms the major component of all results in the semantic similarity calculations.

While some translators faithfully mirror the original text, capturing the unique aspects of ancient Chinese naming conventions, this approach may necessitate additional context or footnotes for readers unfamiliar with these conventions. Conversely, certain translators opt for consistency in translating personal names, a method that boosts readability but may sacrifice the cultural nuances embedded in The Analects. The simplification of personal names in translation inevitably affects the translation of many dialogues in the original text. This practice can result in the loss of linguistic subtleties and tones that signify distinct identities within particular contexts. Such nuances run the risk of being overlooked when attempting to communicate the semantics and context of the original text.

Understanding Semantic Analysis – NLP

You can proactively get ahead of NLP problems by improving machine language understanding. Natural language processing brings together linguistics and algorithmic models to analyze written and spoken human language. Based on the content, speaker sentiment and possible intentions, NLP generates an appropriate response. With its ability to process large amounts of data, NLP can inform manufacturers on how to improve production workflows, when to perform machine maintenance and what issues need to be fixed in products. And if companies need to find the best price for specific materials, natural language processing can review various websites and locate the optimal price.

88 classes have had their primary class roles adjusted, and 303 classes have undergone changes to their subevent structure or predicates. Our predicate inventory now includes 162 predicates, having removed 38, added 47 more, and made minor name adjustments to 21. All of the rest have been streamlined for definition and argument structure. The first major change to this representation was that path_rel was replaced by a series of more specific predicates depending on what kind of change was underway.

For those state changes that we construe as punctual or for which the verb does not provide a syntactic slot for an Agent or Causer, we use a basic opposition between state predicates, as in the Die-42.4 and Become-109.1 classes. • Verb-specific features incorporated in the semantic representations where possible. The difference between the two is easy to tell via context, too, which we’ll be able to leverage through natural language understanding. With the help of semantic analysis, machine learning tools can recognize a ticket either as a “Payment issue” or a“Shipping problem”. In simple words, we can say that lexical semantics represents the relationship between lexical items, the meaning of sentences, and the syntax of the sentence. Expert.ai’s rule-based technology starts by reading all of the words within a piece of content to capture its real meaning.

It involves processing natural language datasets, such as text corpora or speech corpora, using either rule-based or probabilistic (i.e. statistical and, most recently, neural network-based) machine learning approaches. The goal is a computer capable of “understanding” nlp semantics the contents of documents, including the contextual nuances of the language within them. The technology can then accurately extract information and insights contained in the documents as well as categorize and organize the documents themselves.

For this reason, Kazeminejad et al., 2021 also introduced a third “relaxed” setting, in which the false positives were not counted if and only if they were judged by human annotators to be reasonable predictions. To accomplish that, a human judgment task was set up and the judges were presented with a sentence and the entities in that sentence for which Lexis had predicted a CREATED, DESTROYED, or MOVED state change, along with the locus of state change. The results were compared against the ground truth of the ProPara test data. If a prediction was incorrectly counted as a false positive, i.e., if the human judges counted the Lexis prediction as correct but it was not labeled in ProPara, the data point was ignored in the evaluation in the relaxed setting. To get a more comprehensive view of how semantic relatedness and granularity differences between predicates can inform inter-class relationships, consider the organizational-role cluster (Figure 1).

As mentioned earlier, not all of the thematic roles included in the representation are necessarily instantiated in the sentence. Natural language processing and Semantic Web technologies have different, but complementary roles in data management. Combining these two technologies enables structured and unstructured data to merge seamlessly. This study employs natural language processing (NLP) algorithms to analyze semantic similarities among five English translations of The Analects.

Data Structures and Algorithms

Transitions are en, as are states that hold for only part of a complex event. These can usually be distinguished by the type of predicate-either a predicate that brings about change, such as transfer, or a state predicate like has_location. Our representations of accomplishments and achievements use these components to follow changes to the attributes of participants across discrete phases of the event.

  • Despite this structural change slightly impacting the semantic similarity with other translations, it did not significantly affect the semantic representation of the main body of The Analects when considering the overall data analysis.
  • The meanings of words don’t change simply because they are in a title and have their first letter capitalized.
  • The data displayed in Table 5 and Attachment 3 underscore significant discrepancies in semantic similarity (values ≤ 80%) among specific sentence pairs across the five translations, with a particular emphasis on variances in word choice.
  • NLP can also scan patient documents to identify patients who would be best suited for certain clinical trials.
  • I say this partly because semantic analysis is one of the toughest parts of natural language processing and it’s not fully solved yet.
  • Speech recognition, for example, has gotten very good and works almost flawlessly, but we still lack this kind of proficiency in natural language understanding.

For comparative analysis, this study has compiled various interpretations of certain core conceptual terms across five translations of The Analects. Since each translation contains 890 sentences, pairing the five translations produces 10 sets of comparison results, totaling 8900 average results. “Automatic entity state annotation using the verbnet semantic parser,” in Proceedings of The Joint 15th Linguistic Annotation Workshop (LAW) and 3rd Designing Meaning Representations (DMR) Workshop (Lausanne), 123–132.

Understanding Frame Semantic Parsing in NLP

Lastly, work allows a task-type role to be incorporated into a representation (he worked on the Kepler project). A final pair of examples of change events illustrates the more subtle entailments we can specify using the new subevent numbering and the variations on the event variable. Changes of possession and transfers of information have very similar representations, with important differences in which entities have possession of the object or information, respectively, at the end of the event.

Most of the semantic similarity between the sentences of the five translators is more than 80%, this demonstrates that the main body of the five translations captures the semantics of the original Analects quite well. Once our fundamental structure was established, we adapted these basic representations to events that included more event participants, such as Instruments and Beneficiaries. This also eliminates the need for the second-order logic of start(E), during(E), and end(E), allowing for more nuanced temporal relationships between subevents. The default assumption in this new schema is that e1 precedes e2, which precedes e3, and so on. When appropriate, however, more specific predicates can be used to specify other relationships, such as meets(e2, e3) to show that the end of e2 meets the beginning of e3, or co-temporal(e2, e3) to show that e2 and e3 occur simultaneously.

The meanings of words don’t change simply because they are in a title and have their first letter capitalized. NLU, on the other hand, aims to “understand” what a block of natural language is communicating. In this task, we try to detect the semantic relationships present in a text. Usually, relationships involve two or more entities such as names of people, places, company names, etc. In this component, we combined the individual words to provide meaning in sentences.

See Figure 1 for the old and new representations from the Fire-10.10 class. With the aim of improving the semantic specificity of these classes and capturing inter-class connections, we gathered a set of domain-relevant predicates and applied them across the set. Authority_relationship shows a stative relationship dynamic between animate participants, while has_organization_role shows a stative relationship between an animate participant and an organization.

Temporal sequencing is indicated with subevent numbering on the event variable e. The analysis of sentence pairs exhibiting low similarity underscores the significant influence of core conceptual words and personal names on the text’s semantic representation. The complexity inherent in core conceptual words and personal names can present challenges for readers. To bolster readers’ comprehension of The Analects, this study recommends an in-depth examination of both core conceptual terms and the system of personal names in ancient China.
