The article deals with natural language processing, namely that of an English sentence. The article describes the problems, which might arise during the process and which are connected with graphic, semantic, and syntactic ambiguity. The article provides the description of how the problems had been solved before the automatic syntactic analysis was applied and the way, such analysis methods could be helpful in developing new analysis algorithms. The analysis focuses on the issues, blocking the basis for the natural language processing — parsing — the process of sentence analysis according to their structure, content and meaning, which aims to analyze the grammatical structure of the sentence, the division of sentences into constituent components and defining links between them.

The katoba ritual as a form of oral tradition from the Muna tribe is an integral part of the culture of the supporting community.  The purpose of this study is to describe the structure of the ritual text speech of the Muna communities.  The structure of the ritual speech utterances in this study is called the pogau toba text (PTT). This study uses a qualitative method with a Van Dijk structural approach that focuses on three frameworks of text structure, namely macro structure, superstructure, and microstructure. The results showed that 1) the macro structure, which is the overall meaning, global meaning, or general meaning of the PTT. The macro structure found in the PTT is the inauguration of a child as a Muslim. This is reflected in the pronunciation of the two words of the shahada of Asyhadu Allah ilaha Ilallah wa ashadu anna Muhammadar Rasulullah which marks a person's Islamic status; 2) superstructure, namely the four main flow structure of PTT in the context of the katoba ritual, namely opening “pembukaan”, toba conditions “syarat-syarat toba”, core of toba “inti toba”, and the closing “penutup”;  and 3) microstructure, which is limited to the style of the PTT language, namely diction or choice of words in the katoba ritual emphasizing religious and moral elements that are concrete through the use of polite and gentle language, found also a parallelism in grammatical structure, and expressions metaphorical expressions that take the symbols of flora and fauna or other natural objects are presented to convey an idea, concept, or specific purpose.

The processing of words containing inflectional affixes triggers morphophonological parsing and affix-related grammatical information processing. Increased perceptual complexity related to stem-affix parsing is hypothesized to create predominantly domain-general processing demands, whereas grammatical processing primarily implicates domain-specific linguistic demands. Exploiting the properties of Russian morphology and syntax, we designed an fMRI experiment to separate out the neural systems supporting these two demand types, contrasting inflectional complexity, syntactic (phrasal) complexity, and derivational complexity in three comparisons: (a) increase in parsing demands while controlling for grammatical complexity (inflections vs. phrases), (b) increase in grammatical processing demands, and (c) combined demands of morphophonological parsing and grammatical processing (inflections and phrases vs. derivations). Left inferior frontal and bilateral temporal areas are most active when the two demand types are combined, with inflectional and phrasal complexity contrasting strongly with derivational complexity (which generated only bilateral temporal activity). Increased stem-affix parsing demands alone did not produce unique activations, whereas grammatical structure processing activated bilateral superior and middle temporal areas. Selective left frontotemporal language system engagement for short phrases and inflections seems to be driven by simultaneous and interdependent domain-general and domain-specific processing demands.

It has been suggested that there is less difference between ancient Greek and modern Greek than between present-day English and Chaucer's language. The suggestion is somewhat questionable. Broadly speaking, apart from dialects and local variations, there are presently three languages in Greece, the Kathareuousa, the Demotiki, and the popular newspaper language, which is a blend of the two.The Kathareuousa is the official and formal language, used in Government publications and statements, business correspondence, non-fictional books and treatises, law courts, University lectures, and in formal conversation. And although its grammatical structure is analytic as opposed to the synthesis of ancient Greek (a change which constitutes the main difference between classical and modern Greek, as it does between other modern and ancient languages), in the Kathareuousa the most strenuous attempt has been made to maintain the accidence and vocabulary of the ancient language.Words are declined and verbs conjugated (without some of their more difficult and less used moods and tenses) as in Attic Greek, pronouns and prepositions and the cases governed by them are the same, and while, naturally, many terms which describe things known only to the modern world are not to be found in Liddell and Scott, they are generally legitimate and intelligible compounds of words which are to be found in Liddell and Scott. Ἀɛροπλἁνoν for aeroplane, ἀɛρòσTαtoν for balloon, are instances which come easily to mind.

AbstractRecent groundbreaking work in cognitive linguistics has revealed the semantic complexity of motion metaphors of time and of temporal frames of reference. In most approaches the focus has been on the clause-level metaphorical meaning of expressions, such as Moving Ego (We are approaching the end of the year) and Moving Time (both Ego-centered, as in The end of the year is approaching and field-based, as in Boxing Day follows Christmas Day). The detailed grammatical structure of these metaphorical expressions, on the other hand, has received less attention. Such details include both elements that contribute to the metaphorical meaning and those that have a non-metaphorical temporal function, e. g., tense and (central features of) aspect. I propose a model for the analysis of metaphorical expressions, building on earlier work in Conceptual Metaphor Theory and the framework of Cognitive Grammar (CG). I approach the grammatical structure of metaphorical expressions by analyzing the interplay between veridical and metaphorical systems of expressing temporal relations. I argue that these systems relate to two relevant conceptualizations of time. Veridical time (VT) is the non-metaphorical conceptualization of time, where the processual profile of the clause-level metaphorical expression resides. A metaphorical path (MP) is the metaphorical conceptualization of time as a path occupied by the metaphorical motion. A motion metaphor of time tracks the mover’s changing position on the MP against VT. I show how metaphorical expressions based on a motion verb differ from those based on a prepositional construction in grammatical and semantic terms, and how tense and aspect contribute to the conceptualization of the motion scenario. I argue that tense grounds the metaphorical motion event with respect to the speech event. All the participants in the motion event, as well as the metaphorical path itself, are present in each subsequent configuration tracked against VT by the conceptualizer. Thus tense has a wide scope over the motion scenario with Ego’s ‘now’ as a reference point, while Ego’s ‘now’ cannot serve for grounding of tense. This is why expressions such as *The meeting is difficult ahead of us are not acceptable.

AbstractDuring language comprehension, the brain processes not only word meanings, but also the grammatical structure—the “syntax”—that strings words into phrases and sentences. Yet the neural basis of syntax remains contentious, partly due to the elusiveness of experimental designs that vary structure independently of meaning-related variables. Here, we exploit Arabic’s grammatical properties, which enable such a design. We collected magnetoencephalography (MEG) data while participants read the same noun-adjective expressions with zero, one, or two contiguously-written definite articles (e.g., ‘chair purple’; ‘the-chair purple’; ‘the-chair the-purple’), representing equivalent concepts, but with different levels of syntactic complexity (respectively, indefinite phrases: ‘a purple chair’; sentences: ‘The chair is purple.’; definite phrases: ‘the purple chair’). We expected regions processing syntax to respond differently to simple versus complex structures. Single-word controls (‘chair’/‘purple’) addressed definiteness-based accounts. In noun-adjective expressions, syntactic complexity only modulated activity in the left posterior temporal lobe (LPTL), ~ 300 ms after each word’s onset: indefinite phrases induced more MEG-measured positive activity. The effects disappeared in single-word tokens, ruling out non-syntactic interpretations. In contrast, left anterior temporal lobe (LATL) activation was driven by meaning. Overall, the results support models implicating the LPTL in structure building and the LATL in early stages of conceptual combination.
