Semantic-Text-Analysis API Documentation dandelion

We do not present the reference of every accepted paper in order to present a clear reporting of the results. After the selection phase, 1693 studies were accepted for the information extraction phase. In this phase, information about each study was extracted mainly based on the abstracts, although some information was extracted from the full text. Therefore, the goal of semantic analysis is to draw exact meaning or dictionary meaning from the text. However, machines first need to be trained to make sense of human language and understand the context in which words are used; otherwise, they might misinterpret the word “joke” as positive.

Finding HowNet as one of the most used external knowledge source it is not surprising, since Chinese is one of the most cited languages in the studies selected in this mapping (see the “Languages” section). As well as WordNet, HowNet is usually used for feature expansion [83–85] and computing semantic similarity [86–88]. Specifically for the task of irony detection, Wallace presents both philosophical formalisms and machine learning approaches. The author argues that a model of the speaker is necessary to improve current machine learning methods and enable their application in a general problem, independently of domain. He discusses the gaps of current methods and proposes a pragmatic context model for irony detection. Jovanovic et al. discuss the task of semantic tagging in their paper directed at IT practitioners.

Create Smart Content with Machine-Processable Marginalia

Dandelion API easily scales to support billions of queries per day and can be adapted on demand to support custom and user-defined vocabularies. Algorithms split sentences and identify concepts such as people, things, places, events, numbers, etc. Challenges in data analysis and gain the competitive advantage with the power of data. Exploring to find synonyms or words similar in meaning to the word in the query. For example, does “crane” have synonyms or does “crane” belong to a class of “construction automobile”.

What is a good example of semantic memory?

Semantic: Semantic memory refers to your general knowledge including knowledge of facts. For example, your knowledge of what a car is and how an engine works are examples of semantic memory.

The researchers conducting the study must define its protocol, i.e., its research questions and the strategies for identification, selection of studies, and information extraction, as well as how the study results will be reported. The main parts of the protocol that guided the systematic mapping study reported in this paper are presented in the following. In this step, raw text is transformed into some data representation format that can be used as input for the knowledge extraction algorithms. The activities performed in the pre-processing step are crucial for the success of the whole text mining process. The data representation must preserve the patterns hidden in the documents in a way that they can be discovered in the next step. In the pattern extraction step, the analyst applies a suitable algorithm to extract the hidden patterns.

Critical elements of semantic analysis

To contextualize these common threads between research approaches, we examined a paper by Phillip Drieger that laid out the main definitions and terminology used in network science text analysis. Primarily, Drieger extensively defined semantic text analysis and semantic networks. A semantic network is a network where nodes represent text fragments in a data set and edges represent the similarity between those texts. Some semantic networks are two-mode, where one set of nodes correspond to text fragments, and the other set of nodes correspond to the texts themselves. Semantic analysis is a subgroup of automated network analysis where network statistics are used to categorize natural language text data based on criteria set by the researcher.

A semi-automatic ontology construction method from text corpora in the domain of radiological protection that is composed of revelation of the significant linguistic structures and forming the templates. Performance of an interpreter uncovering meanings of prepositions in “master” – preposition – “slave” constructions is described and how performance of the analyzer can be improved with implementation of new rules. A proposal for an integrated framewoek capable of aggregating IoT data with diverse data types.

Semantic Analysis, Explained

In the larger context, this enables agents to focus on the prioritization of urgent matters and deal with them on an immediate basis. It also shortens response time considerably, which keeps customers satisfied and happy. Semantic and sentiment analysis should ideally combine to produce the most desired outcome. These methods will help organizations explore the macro and the micro aspects involving the sentiments, reactions, and aspirations of customers towards a brand. Thus, by combining these methodologies, a business can gain better insight into their customers and can take appropriate actions to effectively connect with their customers. Once that happens, a business can retain its customers in the best manner, eventually winning an edge over its competitors.

The second most frequent identified application domain is the mining of web texts, comprising web pages, blogs, reviews, web forums, social medias, and email filtering [41–46]. The high interest in getting some knowledge from web texts can be justified by the large amount and diversity of text available and by the difficulty found in manual analysis. Nowadays, any person can create content in the web, either to share his/her opinion about some product or service or to report something that is taking place in his/her neighborhood. Companies, organizations, and researchers are aware of this fact, so they are increasingly interested in using this information in their favor. Some competitive advantages that business can gain from the analysis of social media texts are presented in [47–49]. The authors developed case studies demonstrating how text mining can be applied in social media intelligence.

Semantic analysis methods will provide companies the ability to understand the meaning of the text and achieve comprehension and communication levels that are at par with humans. The semantic analysis uses two distinct techniques to obtain information from text or corpus of data. The first technique refers to text classification, while the second relates to text extractor. Lexical semantics‘ and refers to fetching the dictionary definition for the words in the text. Each element is designated a grammatical role, and the whole structure is processed to cut down on any confusion caused by ambiguous words having multiple meanings.


The review reported in this paper is the result of a systematic mapping study, which is a particular type of systematic literature review . Systematic literature review is a formal literature review adopted to identify, evaluate, and synthesize evidences of empirical results in order to answer a research question. It is extensively applied in medicine, as part of the evidence-based medicine . This type of literature review is not as disseminated in the computer science field as it is in the medicine and health care fields1, although computer science researches can also take advantage of this type of review. We can find important reports on the use of systematic reviews specially in the software engineering community . Other sparse initiatives can also be found in other computer science areas, as cloud-based environments , image pattern recognition , biometric authentication , recommender systems , and opinion mining .

Semantic Classification Models

Dandelion API is a semantic text analysis of semantic APIs to extract meaning and insights from texts in several languages . The relationships between the extracted concepts are identified and further interlinked with related external or internal domain knowledge. All recognized concepts are classified, which means that they are defined as people, organizations, numbers, etc. Next, they are disambiguated, that is, they are unambiguously identified according to a domain-specific knowledge base. For example, Rome is classified as a city and further disambiguated as Rome, Italy, and not Rome, Iowa.

network science methods

This lexical resource is cited by 29.9% of the studies that uses information beyond the text data. WordNet can be used to create or expand the current set of features for subsequent text classification or clustering. The use of features based on WordNet has been applied with and without good results [55, 67–69].

hamming distance

The difficulty inherent to the evaluation of a method based on user’s interaction is a probable reason for the lack of studies considering this approach. Despite the fact that the user would have an important role in a real application of text mining methods, there is not much investment on user’s interaction in text mining research studies. A probable reason is the difficulty inherent to an evaluation based on the user’s needs. Text mining is a process to automatically discover knowledge from unstructured data. Nevertheless, it is also an interactive process, and there are some points where a user, normally a domain expert, can contribute to the process by providing his/her previous knowledge and interests.
