Some studies (e.g., Wierzbicka, 1996) have aimed to figure out how a large number of concepts in the mind can be neatly organized with a basic set of concepts, leading us to the realm of human cognition. Furthermore, some studies have identified a set of base concepts that have had a wide range of computational applications. 1 WordNet (Miller et al., 1990) , for instance, is organized around a set of base concepts (i.e., SuperSenses), with which a large number of lexical items are associated through lexical relations. There have been many 58 Chan- Chia Hsu & Shu-Kai Hsieh approaches to exploring what is basic in the mind, but there has been no consensus as to what constitutes a set of base concepts universal to all human languages.",

Since the glosses in the Chinese Wordnet use basic words, words that occur frequently in the glosses of the Chinese Wordnet can be assumed to be reflective of a candidate set of base concepts. After data extraction and introspection, the resulting set of base concepts in the present study is compared with the set of Base Concepts proposed in the EuroWordNet project (Vossen et al., 1998) . In selecting a set of base concepts, our method is based on the frequencies of words used in the glosses of the Chinese Wordnet, whereas the method adopted in the EuroWordNet project is based on the relations between synsets. It is thus noted that the set of Base Concepts in EuroWordNet is not seen as de facto, but as a reference. We use the Base Concepts in EuroWordNet as our reference because on the one hand, the Chinese Wordnet and EuroWordNet both derive from the WordNet framework, and on the other hand, the set of Base Concepts from EuroWordNet is based on many European languages. It is hoped that both the overlap and the difference between different sets of base concepts identified by different approaches can deepen our understanding of the basic core in the mind. Additionally, it is also hoped that the set of base concepts identified in the present study can have computational as well as pedagogical applications in the future. This paper is organized as follows. Section 2 provides a comprehensive review of different approaches to the notion of basicness in the mind. Section 3 reviews the significance of glosses in different contexts. Section 4 introduces our experiment method and presents the set of base concepts identified in the present study. Section 5 discusses how our proposed set of base concepts in Chinese is different from that of EuroWordNet. Section 6 concludes the paper.",

With the rapid development of computational analyses, such lists are mostly based on frequency counts. They can serve as useful references for pedagogical purposes, such as the design of a syllabus and the development of a language proficiency test. The main problem with most basic vocabulary lists is that the raw data on which the frequency counts are based may not be representative enough. Additionally, since what counts as a word is an issue in itself, an insight is needed when it comes to word forms and lexicalized phrases (McCarthy, 1999) .",

From a cognitive perspective, it is suggested that there is an innate set of semantic primitives representing \"a universal set of fundamental human concepts\" (Wierzbicka, 1996:13) . Such a set is argued to be sufficient to define or paraphrase the entire vocabulary of a language. For example, the word envy can be defined as what follows (Wierzbicka, 1996:161 Goddard (2002:14) has presented 58 \"atoms of meaning\", such as I, YOU, SOMEONE, PEOPLE, SOMETHING/THING, and BODY. Unfortunately, this line of research is open to valid criticisms due to a lack of a sound method of identifying semantic primitives (e.g., Riemer, 2006) .",

In the architecture of English WordNet, synonyms are assembled in a set called synset (synonymous set). During the development of WordNet, synsets are organized into 45 lexicographical files based on the criteria of syntactic category and logical groupings. The 45 names of lexicographical files (e.g., noun.feeling and verb.cognition) are also called SuperSenses, which reveal the base concepts from the developer's perspectives. 5 As an extension of the wordnet model, EuroWordnet further proposes a set of 1,024 core synsets -called Base Conceptsthat are extracted from four wordnets and translated into the closest WordNet 1.5 synsets. To keep the set balanced and shared among these wordnets, 164 core base concepts of them were selected in terms of their (more) relations with other concepts and (higher) position in the hierarchy. 6 Based on the Base Concepts identified for EuroWordNet, the BalkaNet project adopts a similar approach and selects a set of Base Concepts by focusing on five Balkan languages, including Bulgarian, Greek, Romanian, Serbian, and Turkish. 7",

The term 'definition' would be a misnomer if it implies that word's meaning can be precisely pinned down. There are many strategies to define a word in a dictionary (Lew & Dziemianko, 2006) . The most traditional definition in a dictionary is the analytical model, i.e., the genus-differentia definition. A definition composed in this way typically consists of two elements: the genus expression that locates the definiendum in the proper semantic category, and the differentia (or plural form differentiae) that indicates the information which makes the word differ from other words of the same semantic category. For example, appraisal is defined as \"a statement or opinion judging the worth, value or condition of something\" (taken from Longman Dictionary of Contemporary English), where 'a statement or opinion' is the genus expression and the postmodifying expression 'judging the worth, value or condition of something' is the differentia. In many cases, it is not an easy task to produce a genus-differentia definition, and such a definition can be difficult for a dictionary user to understand. Another way to define a word in a dictionary is to adopt a contextual definition. A contextual definition of 'appraisal', for example, is stated as \"if you make an appraisal of something, you consider it carefully and form an opinion about it\" (taken from Collins COBUILD Advanced Dictionary of English).",

In addition, the effectiveness of dictionary definitions can be evaluated from the user's viewpoint (Cumming et al., 1994; Lew & Dziemianko, 2006) . For example, language learners have been found to prefer contextual definitions to analytical ones (Cumming et al., 1994 ). An interim conclusion thus worth drawing is that a definition should contain no more words than necessary, consistent with the demands of intelligibility and information-transfer (Atkins & Rundell, 2008) .",

Glosses and example sentences are two essential components in the construction of lexical resources like WordNet, for they have been proved to be highly useful in discovering semantic relations and word sense disambiguation tasks (Kulkarni et al., 2010) . In the design of WordNet, word lemmas are grouped into synsets (synonymous sets), which are organized as a lexical network by a wide range of lexical relations (e.g., hyponymy and antonymy). The role of glosses is thus to explain explicitly the meaning of synsets which lexically encode the human concepts.",

For example, glosses are easier to understand than formal representations, so ontology developers from different fields can rely on glosses to a certain degree when they communicate. However, as Jarrar (2006) further suggests, a gloss in an ontology is not intended to provide some general comments about a concept, as a traditional definition in a dictionary does. Instead, a gloss in an ontology functions in an auxiliary manner, providing some factual knowledge that is critical to the understanding of a concept but can be difficult to formalize explicitly and logically. As a consequence, glosses in a wordnet as a lexical ontology are different from dictionary definitions. Jarrar (2006) provides some guidelines for writing a gloss in an ontology. First, an ontology gloss should start with the upper type of the concept being defined. Second, an ontology gloss should be in the form of a proposition. Third, an ontology gloss should emphasize the distinguishing features of the concept being defined. Fourth, an ontology gloss can include some examples. Fifth, an ontology gloss should be consistent with the formal representation of the concept being defined. Sixth, an ontology gloss should be sufficient and clear. Generally, the glosses in the Chinese Wordnet fulfill the above criteria. Here is an example taken from the Chinese Wordnet:",

The study of the basic lexicon is crucially different from other tasks of lexical acquisition in that unlike the latter where the broad coverage is at issue, the former requires instead fine-grained data to be explored.

For example, both yong 'use' and shiyong 'use' were high on our wordlist, and so were wuti 'object' and wupin 'object'. In deciding whether two words did represent the same concept, the present study counted on the Chinese Wordnet rather than on our own introspection or on further analyses. In the former case, yong 'use' and shiyong 'use' bear the relation of synonymy in the Chinese Wordnet. Therefore, the two words were considered to represent the same concept, and the frequencies of the two words were added together. In the latter case (i.e., wuti and wupin), the two words do not bear the relation of synonymy in the Chinese Wordnet. As a consequence, the two words were listed separately on our wordlist (cf.

Such distinctions appear to be basic, and that is captured in our experiment. Our method extracted more words denoting organizations and institutes than the EuroWordNet project. However, some words extracted in our experiment are not hierarchically high. For example, daxue is just a subcategory of the educational institute. Measurement is an important dimension of semantic primitives. Wierzbicka (1996:44-47) has identified a few quantifiers as semantic primitives. Our experiment identified five words that are not included in the Base Concepts of EuroWordNet: yi and liang are quantifiers, and both are also identified in Wierzbicka (1996) (i.e., ONE and TWO) ; ge and zhong are common classifiers in Chinese; jisuan is a typical verb in the measurement domain.",

For instance, we could create a category for perception, which is intuitively an important dimension. However, in the present study, a category for perception may include no more than shengyin and wundu. Almost all of the members in this category are abstract concepts. The only exception is shengwu. Its literal translation would be \"creature\", so shengwu can seemingly be mapped to the synset {animal 1; animate being 1; beast 1; brute 1; creature 1; fauna 1}. Actually, the two concepts are not the same. In English, creature refers to a living organism that can move voluntarily, as the gloss in WordNet states. On the other hand, shengwu in Chinese refers to any living organism, whether it can move voluntarily or not. Therefore, we decided not to map the two concepts together.

The potential base concepts scatter around the mental lexicon; when we take a different perspective, adopt a different method, and have a different focus, we are very likely to extract a completely different set of concepts. That is why a study like the present one is of great significance. To really touch on the basic core of the mental landscape, we need to try a wide variety of approaches. Concepts surviving in different approaches can be seen as basic in the mind.

Also, the coverage of the Chinese Wordnet may not be comprehensive enough, for the project starts with words with a mid frequency. When EuroWordNet and the Chinese Wordnet are further updated, the resulting sets of base concepts and their comparison may give a different picture accordingly. Second, the gloss language is an issue in a gloss-based study like the present one. As a matter of fact, many words in our frequency wordlist have a low frequency, and many of such words can be replaced by other words with a higher frequency (An, 2009:172-182) . If that is done, there will be fewer words in our wordlist, and the frequencies of some words will become higher. Therefore, a different set of base concepts in Chinese could be yielded.",
